Reminds me of a discussion we had here about this time last year. A member named akaSharkey built an awesome deer cart out of one of those carts you push children in (not the stroller - the one with 3 big wheels) Anyhow, he took the body off that thing and mounted the cart on a hitch on the back of his mountain bike. Perfect for transporting his gear to stand and deer out also.
I have one of those carts and they are incredibly easy to push or pull even full of children. I'm just waiting for the kids to get old enough that I can steal it without my wife noticing it is gone
Sharkey hasn't posted since last March and the pictures he posted of his setup aren't online anymore - but if anyone knows him, have him post the pics.
