I wish I had more time to run off to the woods and hunt but out of normal season it's tough to arrange the time to make the trip to go chase hogs. But, it's not to tough to steal a few minutes each afternoon to fling a couple of arrows if only for the pure pleasure of watching them fly.
I love shooting at critters, and I love 3d but danged if I don't have a lot of fun whacking stuff most people throw in the garbage or use for other purposes.
For me, nothing gives instant gratification like the crunch of a coke can. I shoot them till they literally fall to pieces...then shoot at the pieces. I've got a medication that comes in a super tough bottle of heavy plastic...sucker will take a bunch of punishment before giving up the ghost and makes a challenging target. The smaller gatorade bottles bounce around the field really nice and make the most pleasant "WHUMP" when whacked with a blunt. Bottle caps hung on a string are a great target for humbling you on those days when you think you can't miss. Having a bunch of rescue dogs mean we have those solid rubber "Kong" toys...they go "WHOP" when you hit em, they bounce away for a follow up shot and I've yet to tear one up with anything short of a broadhead...and they'll take those pretty regularly too!
So, outside of stumps/leaves/3d targets, what targets do you use just for fun...for the pure sake of giggling like a kid when you hit it?
