Hunting from the ground is a little tougher but it certainly can be done and it's 10 times exciting to be looking your quarry in the eyes. I prefer a natural ground blind. Blowdowns make good blinds. I set up behind the tree from where I expect to see the deer and just sit on a little folding chair. The blowdown should be enough to break up your outline and allow you to draw on deer that are very close to you. I've never been a fan of comercial ground blines but that in just my preference.

I'm gald you found the sport again. I had a lull from my teen to adult years and I find bow huntig just if not more rewarding now that I'm older.
