Moosehornhunter,
Be careful up there in Mainer country.....unless things have changed, it's against the law to possess a moose skull like the one you have pictured unless you legally drew a permit for hunting. Not sure if that's still the case, but you may want to double check just to be on the safe side. I used to live in Northern Maine and picked up quite a few sheds. A buddy found a really nice winter kill rack (not quite as nice as yours) one day while we were out, but later tossed it back in the woods after finding out it was illegal. (I would have been tempted to chance it I think) Maine wardens have quite the reputation for taking themselves a little too seriously!
Nice sheds by the way. I have a nice set that I estimate is around 54 inches wide. I've never mounted them. I think they look cooler just lying around in my den. We used to snowshoe a lot....your sled definitely allows you to cover more territory.
