I started pulling up the old 20 year old matting on my garage floor. I was pretty well worn out by time I got all of the bikes I am not riding enough rolled out. I did find a ton of dirt, some mold, and a number of various insects which I am sure a few date back to the Jurassic period. The spring project is going to be all new cabinets and shelving and either epoxy or a good floor paint. The matting has held up well but has worn in several high traffic areas and wrinkled badly from temperature change.
