I shoot in my basement. I can get 17-18 yards down there, and I have a solid concrete wall as a back stop. My wife hasn't said anything about it so I'm assuming its ok    :rolleyes:

Thirteen yards in the basement...haven't missed the block or bag yet, in case there is a poured concrete wall to keep it in...

my 10 yard basement range is where I work on my release (and after this year draw tempo).  Shoot one arrow at a time and try to hit very small targets.

my first 3000 arrows were all in that setting.

I use to shoot down the driveway into the garage.  WARNING remove trolling battery from shelve 2 feet above target before attempting 25 yard shot.

25 yds in the basement.  Could get 32 corner to corner but that puts the furnace in serious jeopardy if I lose back tension and shank one to the left.

I have a basement set up... I can get 11 yards if I cuddle up to my washer/dryer.

I have a 8 yard basement setup with a paper tuner and bag target to keep the muscles toned.

I've shot in my old trailer, a small appartment, and an army hotel for five months.  I think it's a great idea.  Good for form, concentration, exercise the muscles...all that good stuff.  Not really the way you'd want to try and tune a new or altered set up, but it's a great way to keep things cooking.
