Tree rats are tons of fun. I used to have to walk on the other side of the tree from my dad (God bless his soul) which pushed the squirrel to his side where, ka-blam! I'd save the tails. Squirrels are where I was first indoctrinated into field dressing game.
I took my kids out last year. Funny thing! My 5-year old son saw no squirrels but lots of moose, tigers, and leopards. Keep in mind we live in southern WI. Good memories.
