Jeff - If you want to leave it there, maybe look into plastic lawn furniture. I use the green plastic chairs that you can buy dirt cheap at Lowes or HomeDepot, especially at the end of summer. Just make sure you can shoot out of them (arms might be in the way), sometimes I've bought the side tables for them and just sit on the table because its good for shooting off of.

I bought a dozen of them a few years ago for about $30, and I leave them in my ground blinds or even my built stands. they are comfy compared to a stool.
