The guy who applied the foam and left the letter is a chicken$hit prick, if ya ain't willing to go face to face then don't bother.
I do find straight-pipe Harleys to be uncalled for, and most of the riders of 'em are a$$holes IME... but Harleys and their riders are fading.
Most irritating thing around here tho are the friggin' Mexican ice cream vans rolling down the street... "ding, ding, ding-ding-ding, ding-a-ling, ding-ding.. HELLO! ...ding, ding, ding-ding-ding, ding-a-ling, ding-ding.. HELLO!... ding, ding, ding-ding-ding, ding-a-ling, ding-ding.. HELLO!..."
.....playing a friggin' BARBIE tune...
I'll take straight pipe Mexican ice cream trucks any day.
