Stuff happens, and I end up with unplanned bike repairs on the side of the road.

I try my best to pick up after myself, although perhaps I'll occasionally lose a valve cap or valve nut (unintentionally).

I don't want to get run off with a shotgun for changing a tire on corner of someone's lawn.

Be POLITE.

Also, I wouldn't expect someone to toss their ruined car tire out in my yard.

If not you, what happens to the next cyclist that comes along and has to fix a flat, or chain, or spoke, and encounter the ire of a homeowner that had to pick up the previous cyclist's litter?
