Call 40 mile air ASAP, tell them you want to hunt in unit 20E. They will know where to take you. If you are lucky the state will issue a emergency order like they did last year. To allow you to hold RC860 permit (caribou) and RM865 permit (moose) some big moose in 20E.
Thanks for that recommendation - I will add them to my list of places to research. I don't think I can swing a hunt this year, however... I should (hopefully) draw the elk tag that I've been waiting 15 years for, so September 2021 will hopefully find me chasing big bulls in the quakies.
