Twin towers is still there. Im assuming your talking about the one right off of Route 2 on the edge of Oregon.
They have 4 25yrd pistol stalls and one rifle stall that is either 75 or 100 yrds.
Shooting of clays or any sort of breakable target is not allowed
Bringing your own target stands is not allowed (there are ones provided)
Other than that as long as common sense tells you that its probably alright then you can probably do it.
Range hours are if the sun is up you can shoot
It is an unmanned range and there is hardly ever anyone there so thats pretty nice
Its a private range and to become a member you need to take a walk out there and pick up a membership form to fill out and mail in. They are in the mail box on the fence (back by the range). If you live a ways away you can shoot me a pm and the next time i get out there ill try to pick one up for you
Membership fees is something like $45 for a year. There are no other fees to shoot.
