I thought so too ! Reg. G . LolGallen, You really had me confused for a bit! I initially thought you wanted information about the Wyoming Range (for hunting info).......a range of mountains, running north/south along Wyoming’s western border!
Now, that we’re on the same page......no information to offer. Sorry! We’ve got one here at Worland 80+ miles south of Cody), that I think goes to 800 or so yards. Which is probably a lot farther than is practical for you! I’m not sure what their guest use policy is though. BLM, after a trip to Walmart for materials....may be your best option. memtb
