For those with ipads, ipod touches, or iphones.....
Three apps that I've found with lots of good information
"state lines" - good information on laws in all States
"Campwhere" - pretty dang good information on camping (all except the most unofficial boondocking)
"RV Parks" - yup, you guessed it, need I say more?
