Are there attempts Showers Padre Island?
I want to camp, but still be able to take a shower when we were in or near South Padre Island, this summer. I can not find anything online that the state and KOA is only for mobile homes there. Also I would be able to make a fire, but the shower is more important! LOL I'm camping with 3 kids and do not want to go to bed of sand stuck in the ass for a week-lol. Suggestions?
Here is a link to a state park camping States with facilities, rather than place http://www.tpwd.state.tx.us/spdest/findadest/parks/mustang_island/ KOA
