I am a teacher from GA. We have spring break the first week of April. Myself, my wife and 2 kids (4 and 3) were wanting to start at LBL and move our way east. Any recommendations after LBL. Probably wont be doing any primitive camping bc of the kids. We were thinking LBL and maybe Mammoth Cave and after that we are wide open. Should we spend a few days at each or would you guys go to other places. Any info would be much appreciated! Thanks!
