When I was up there, I had good luck with Alaska Outdoor Forums
https://forums.outdoorsdirectory.com/ . After checking to make sure it still is a legitimate site, I see you are already advertising there. Not sure what Boondocks charges, but when I was up there, he'd have at least a few on consignment most of the time. Do you have access to a swap board at a credit union or other social type location?
