3 or 4 inches of snow No Problem

Well yesterday we had our first major snowstorm in St. Louis with between 3 to 4 inches. I decided to go out in my powerchair which is a Permobile Chairman 2S. Well I only came close to getting stuck one time, but otherwise I had no problems. Now the first powerchair I had which was an Invacare would get stuck in 1/2 inch of slush and water, real embarrassing.
