I have a New Mexico GMU-13 unit-wide muzzleloader antlerless elk landowner voucher for sale. This allows you to hunt on all public lands in the unit (extensive Forest Service and BLM lands as well as some state lands), and also on any private lands that are enrolled in the New Mexico landowner tag system and have applied for or received unit-wide tags in 2018. There are no centerfire rifle elk hunts on this unit -- only archery and muzzleloader hunts. The antlerless hunt is muzzleloader only. The voucher requires that you choose either the December 1-5 season or the December 8-12 season at the time when the license is purchased.
Price for the voucher is $500, first "I'll take it" post gets the voucher. Listed on other sites as well, so subject to sale there also based on time of first response.
