I will never forget many years ago buying a project '77 Westy that had been sitting a couple of years due to a rotted front beam. It was in January that I decided it was time to get started on it, so early one Saturday morning I drove it into my garage, fired up my kerosene heater and went back into the house for a couple of hours. When I returned the garage was close to 80 degrees, and the heat had awakened MANY wasps who had been nesting in various spots (I think in total I removed 7 wasp nests).
