Most T/A's and Petro's now seem to have clean showers. The worst ones I would say are Pilot and some of the Flying J.
There's one in PA (I think near Pottsville) a pilot. You get in and has almost no hit water. If someone in Pittsburgh flushes a toilet then you get a sudden gush of hot water that lasts for two seconds.
The only bad showers I had at flying j 's where in billings Montana and they where connoco truck stops subsidiary of flying j
Would it kill TA to put in some freakin' counters?!?!?!? I just showered at one in utah. Had an 8ft mirror but only a pedestal sink. don't need that much mirror, but sure would love a counter to lay out my toiletry bag on
Don't stop at Newell's in Newton Kansas, large clean, marble, hot water. You will never be happy with the others
Could the one in Plant City you're thinking of be the old 40 Acre in Lakeland? The only one I know of in Plant City is closed and never had a dirt lot.
