Hi there; I just want to add my experience with ATV vs Snowmobile. I just sold my Snowmobile last year, it was a Yamaha Venture Long Track,excellent for going through the Snow or just hauling the Portable Hut around,however, what Snow??, like many people said before there were times I couldn't go fishing because of luck of Snow. I ended up buying an ATV Traxter,but thats just my preverence. If I were to buy a Snowmobile again it would be a Touring model, a two up model. As per ATV, you'll get as many opinions as ATV's out there to what brand to buy, personaly I thing all major Brands like Bombardier, Yamaha, Polaris are good machines
Have fun looking
