I've been up to spenceville a handful of times, wasn't to bad as far as trash and irresponsible shooters. Just be sure to go before noon, during the week.
Also if you reload, watch your brass, as when the last time I shot at spenceville there was two asians picking up our shells as soon as they hit the ground. I didn't really bother me because I don't reload, but they almost were kind of getting to close for comfort to our firearms sitting on the bench. Anyone else expierence this too?
