We are going to a WWII reunion the beginning of September in San Antonio, TX. Looking for suggestions as to where we can camp with our 20' trailer. Last time we were in TX, I remember the state offered no discounts at all, AARP, AAA, etc. We have evernything including America the Beautiful Senior Pass. Looking for BLM, COE, NP, SP. I've sent for info, but it hasn't arrived yet. And to me, half the fun of traveling is the planning. ..... .
