LAMESA, Texas — I am about to let you in on a little secret, although it’s likely not a secret to veteran RV travelers.

If you want to park your recreational vehicle free of charge, just look for those “public parks” in your RV directory.

We rolled into this West Texas town with a population of about 9,400 residents. We had called ahead when we saw a listing in our RV directory that caught our attention. It was a “public park.” So I called. It turns out the RV park is part of the municipal park system.

The lady at City Hall told me we could stay here for free for a maximum of four nights. It has water and electric hookups; no sewer, but . . . we can take our waste water with us to the next location.

We have found some of these public parks on our travels over the past three or four years. We stayed at one of them in Sayre, Okla.; if memory serves, the nightly rate there was $10, which we considered a heck of a bargain.

While traveling in Texas, we prefer to stay at state-run RV parks. Given that we’re big fans of the Texas Parks & Wildlife Department, we like supporting the state park system. The parks where we’ve stayed over the years have been well-manicured, well-appointed and generally quite gorgeous.

We buy a state park entrance pass once a year to waive our entrance fees. Since we’ve made ample use of the state parks, the pass is worth the investment.

But tonight we’re getting some free room and board at a city park. Keep this kind of thing in mind if you’re like my wife and me and enjoy the open road in your RV.

If you venture to Lamesa, here’s a tip: The locals pronounce the town name La-MEE-sa, not La-MAY-sa.

It must be a Texas thing.
