That's some good ideas for my son, thanks!small hand saw or axe for gathering firewood.... and if you have room, bring some firewood too, sometimes its scarce as everyone else likes a fire too...
for a 4 year old, you might make or buy something to put bugs in.... grass hoppers, fireflies, butterflies - when my son was that age, we made one using, window screen material and some plastic coolade containers, poked holes threw containers and used a needle and thread to attach one end of screeen and left the other loose so that he could remove it to put bugs, leaves, grass.. into it... kept him occupied...
Now, about the firewood issue... My sister told me that there are alot of campgrounds around Florida that will not allow you to have a camp fire, for fear of starting wildfires. Can someone comment on that? Sounds like this is something I'd have to call ahead on, I'd hate to go camping and not be allowed to have a campfire. Kinda takes all the fun out of it....
