Sounds good festus! Because of the snow over here My project came to a hault.....for now. Hope to finish in the spring. No problems here in NH to shoot in Your back yard. I already got ahold of Fish/Game. There is no law in NH that You must post signs around the perimeter of Your property BUT it is a good idea that You do. I'm not going to get into it again because it has already been posted on here.
I still have to go another 5' higher on mine and finish off the sides to make the "U". My signs will say..."KEEP OUT / SHOOTING AREA". As You said, "no range fee's", is a plus in my book! For those who have not seen My photo's, check out the "NH" thread, Backyard Shooting.
festus.....we need photo's!!!
(All the above are MY opinions/suggestions ONLY....AND, I like to bust ball's, it's called having a sense of humor. In other words, no intent to offend anyone, so get over it)
