I find this whole sign thing interesting. According to the website, to adopt a street, you have to go out once a month and clean both sides. The street is at least one km long. You also have to fill out a report in details, along with where the trash can be collected.
As far as I can tell, he's adopted at least three streets (3km + in total). If he can't even walk a few feet without being winded, needs a scootypuff, has seizures, etc... how is he able to clean the roads? I can't imagine he can even bend over to pick something up without huffing and puffing.
