From Pine Junction take 126 go thru Pine and Thru Buffalo Creek. Up the hill and past the turn of for Lake Wellington. As you dip down after the next hill there is a turn off on you RIGHT, marked VERY minutely NF Road 528G ( I think) drive n back and blast away. FYI its no that big, so dont go on a Sat afternoon between 11-4 or else it will be crowded as hell (In my experience).

PS Love the guys who go full auto without even shouldering the weapons.

Have fun!
