My original plans for going to Baja this winter fell through, unless I want to do it alone again. Then I saw this thread, and even though I'm not a huge fan of either the Gulf or Texas, I got thinking, "Hmmmmm, maybe. It would be a change from the AZ desert. And I do like the beach a lot (I'm on the Pacific coast right now). I could do a slow crawl along the Rio Grande to get there, make a bit of a trek of it. Do something new."
I have Marianne Edwards' Frugal Shunpiker's Guide to RV Boondocking in Southern Texas. I got it out to see what she says about the Gulf Coast. Then I used Google Earth to look up the free beach camping spots she mentioned. Some are kind of bleak, but a few were appealing -- at least in photos. And it's not like I'd have to stay there if I didn't like it.
So, I'm still on the fence. If I do it, it will be pretty much on my own. It would be good to meet up with some fellow full-timers, but I'm not good at group socialization. And I suck at caravanning.
