I actually see street cleaning teams here in Germany regularly where one person blows the dirt out from bike racks and from under parked cars and the other person sits in the big street sweeper to pick up the dirt. I think this is a very valid use for blowers. The blowers are electric, but I sure would.not mind them a bit more quiet.
The unfun part is when its your personal rights (personally) and you have to discuss them to defend yourself.
Did they really just cover the whole blister thing with fishmeal? I mean including the plastic?
