Guadalupe State Park or Perdenales ?Our oldest son has our RV this week at GSP. We want to go up and take over on Sunday. I want to stay there, DH wants to go to Perdenales. My main goal is to float float float. From what I remember is PF is very shallow and rocky and not for floating. Pictures seem to back me up but they swear you float on the lower part of PF. Anyone know ??
