Ninety-one. That’s how many days my parents spent in their motor home in 2004.

My dad often likes to remind me of this fact — and his goal of surpassing it by the end of this year.

My parents retired just after I entered college, and like most older folks, have found an activity that makes them happy. In their case, it’s traveling and camping in their RV.

Part of my parents’ winter routine now includes two months of travel around the state of Florida from campground to campground.

So when they invited me to spend Spring Break with them this year, I knew the trip was going to be far from ordinary. Let me walk you through just 24 hours of the experience, and I think you’ll see what I mean …

When I arrived on Saturday afternoon at the Orlando airport, my parents rushed me back to the Rock Crusher Canyon RV Park near Crystal River, FL. We would be spending our first three nights of the trip at a Roadtrek rally.

OK, I know. I need to explain a few things. Technically, my parents’ RV brand is called a Roadtrek — and don’t confuse it with a Winnebago or a Prevost. RVers are very brand loyal. And yes, I said a rally. Most every RV company throws rallies all over the country. It’s when a group of 25 to as many as 300 units (aka RVs) get together for a few days at a certain campground. The rally coordinators arrange for meals, entertainment and sightseeing for whatever place the rally is held in. And the most exciting part — the showing of new models, complete with RV experts who give tours of these models and demonstrations about how to use and fix all the new features in them.

Luckily, nothing was scheduled for that first night, and I was looking forward to a quiet evening catching up with my parents.

But my mother — clad in her tie-dyed “Bash at the Big House” T-shirt — thought it’d be more fun to practice piano.

Wait, a piano? In an RV? Yes, again. My parents have a small trailer they pull behind our RV (it’s outfitted with the same decals as the main unit and has “trek it” painted on the side). It houses two lawn chairs and my mother’s giant professional keyboard.

After my dad hauled the keyboard out and set it up next to our campfire, my mom began to play. I sat there mortified and thanking God that no other 20-somethings were nearby to see this peculiar sight when an older couple walked up.

“Nice music,” the man said, “Mind if my wife and I join you?”

Over the next half hour, several more couples were lured to our campsite by my mom’s music — which I must admit is quite good. And before long, we had ourselves an all-out sing-a-along, complete with requests being taken and “guest” pianists taking their turn at the keyboard.

While my mom entertained our new “friends,” I sat apart from the campfire circle and played games on my laptop.

“Writin’ a letter to your boyfriend on the internet?!” one of the men asked, looking back at me and giving a little wink.

“Oh, no. Just playing games,” I countered and tried hard to stifle a laugh. Honestly, who else from Michigan was getting hit on by an 80-year old man at that very moment?

At about 10 p.m., everyone had left to walk back to their own RVs. For us, it was (of course) time for bed, and I was looking forward to a quiet night’s sleep … except that our RV only has one bed. My mom, my dad and I looked like sardines next to one another as we dozed off on that king-sized mattress. I woke up once having to use the bathroom … but on second thought decided that maneuvering out of and back into the bed wouldn’t be worth the trouble.

The next morning, memories of chilly wake-ups while camping with my parents in high school suddenly came back to me as I shivered in my sleeping bag. It was 6:30 a.m. and my mother was already asking me to move so she could set up the table for breakfast.

My parents’ RV is a smaller model, and even though it has a bed, kitchen, toilet and wardrobe, many things serve a dual purpose — in this case, the bed turns into a table or a couch, depending on what you need at the moment.

“Why don’t you go take a shower?” my mom suggested. So I grabbed a towel and bravely set out to find the bath house.
