I know it's far too early to think about any snow sports but when I saw the Camoplast Giant ATV Track System at OhGizmo, I was actually excited about winter again! The Camoplast retrofit allows you to equip your current ATV with tracks similar to a tank. Too bad I live in Sunny California and not Indiana anymore because I'd love to try this out!
From OhGizmo: Besides making you look like the guy who spends more money on his ATV than his car the Camoplast system does provide higher ground clearance and a larger ground surface making them well suited to all four seasons, especially snow. Installation of the tracks will take about two to four hours depending on your skillset and apparently allows the original wheels to be easily put back on when needed.
