good ideas guys...Trembow...ill be very very careful...im actually a pretty over careful guy...my neighbors all have fences...so thats 2 layers of thick wood fencing.....i like the idea of builing a wooden "shack" type thing to hold the bales.....and i can layer carpet in the back of it...and hang a few layers infront of the bales...and make it pretty decint sized to stop anything with the worst misses..though i know anything can happen...our fences are all high also...they are 7 foot high i believe.....i wish the stickin pool wasnt where it is....i have a concret garge back there i can put the targets in and blast away at them...i think ill probably build it on the back side...noone will see it....and theres a perfect 8foot gap between the shed and garage on both sides......so if something would go stray it will hit the garage or shed...then right into the backstop......ill hafta talk to dad when the time comes....think thats my best bet though...and should be more then safe...
