Road and Track is just a short drive west. Stopped there one time just to pick up a seat I bought on Ebay from them. They are a supporter of the site so and have a banner ad so if you click on that it will take you to their website and you should be able to learn more about them. Not sure they are a true dealer or more of a secondary seller and a lot of used inventory, but I bet they had 150 sleds when I was there.
Road Track and Trail does have a huge inventory of used sleds and they became an Arctic Cat dealership about 5 years ago.
They are about 1/2 hr. west of Milw metro area on National Ave.
I like the fact that they have all types a rec. vehicles so any type a trade-in is welcome.
I have had good experience with them.
Sportland II is in Oak Creek a southern suburb of Milw.
