If all the melting snow and slop has you in need of a car wash, just drive to the end of the Gunflint Trail near the Canadian border in the BWCA wilderness and park your car on the side of the road in the burned out region between Gunflint and Saganaga Lake. The moose will be with you shortly … however it is important to have salt on your car as the moose do not accept cash for payment.
Just after dark Saturday evening while picking up my boys at Saganaga Lake after their winter trek from Moose Lake near Ely to the Gunflint, three cars in succession got the “lick treatment” from two different moose! 
I kind of feel like I should feature my boys. Skiing / snowshoeing 40 miles through the BWCA is a big deal. On the portages even with snowshoes the snow was up to their hips. Uff dah! When we had our celebratory dinner at Trail Center Lodge, the owners were so impressed with Carl and Erik, they offered to formally sponsor them for their next trek into the wilderness!
Dad (i.e. me) made certain I had two beers waiting for the boys when they finished! One quick aside, the Garmin InReach satellite communicators worked like a charm. Carl and Erik check in each evening and let us know all was fine. During the final day’s trek, they kept us updated on estimated time to the boat landing. This allowed Molly and me to be waiting when they finished. 
Congrats Carl and Erik! I would love to hear more detail of your winter camping. What were the biggest joys and challenges? Did you see any wildlife such as birds?😉
Maggie: In talking with my boys, the biggest challenge were the portages between various lakes. The streams had open water, which is normal even with all our cold weather. Thus, they had to use the canoe portages. This winter’s snowpack was so deep, that even with snowshoes, a 80 rod portage would take an hour to complete. The same deep snow has meant no dogsled teams have ventured deep into the BWCA as no musher wanted to be the first to break trail. Thus, my boys broke trail. In years with less snow, there are often some dogled trails to follow into the heart of the BWCA.
Your sons accomplished an an amazing feat. And thanks for letting me share your moose-wash post to Gunflint Trail Nature and Notes… got a lot of appreciation.
