My buddy and I will be in Big Sky skiing from March 5 through March 8, but wish to go snowmobiling in Yellowstone Park for a day. Looking anyone who would like to join us to reduce cost. I'd like to rent snowmobiles in West Yellowstone, but understand that to go into the Park, you need a guide. Most tours go to either Old Faithful, or the Grand Canyon of Yellowstone, but not both. To do both, this can only be accomplished by having a guide. Guide cost400 alone, plus rental cost of sleds and cloting. Looking for anyone who may be interested in joining us to form a group to do the Yellowstone Loop which includes the Grand Canyon of Yellowstone, and Old Faithful, and reduce the cost per person for the gudie. Back in the 80's I was able to simply rent a sled and was free to ride where I wanted in the Park. These days, laws have changed and you need a guide if you want to do the loop. If interested, please let me know and we'll see what we can work out.
