I am a fan of nature myself. Just a warning though, be careful of trees that have ants or spiders running up and down them. I used to bow hunt and I would get way up in a tree to avoid being detected easily by the deer. I always came across something along the way that I didn't care to be bitten by... and I'm sure that would ruin the whole experience. I know, I know... I'll stop with the public safety announcement. BTW, I no longer hunt now.
My six year old daughter is the same way all of you described your kids to be... it is too temporary of a wonderful feeling.
