I NEVER park on a public sidewalk. It is against the law and I don't need a bloody ticket. Around here you get one if you try that. I know. Personal experience is a remarkable teacher.
BUT, almost all the parking lots here are blacktop and most, I hate to say it, "motorcyclists" are incredibly dense when it comes to carrying a "cycle foot" or other side stand pad with them. (Can that really be so HARD to do? Is it a right to be inconsiderate of the business' property to say nothing of the possibility of the bike tipping over as it sinks into the ooze of asphalt on a hot day?)
So most of the businesses and our only big Mall encourage us to park on the concrete sidewalk, and even designate areas of sidewalk where we can park.
Wal-Mart here had an interesting situation. When they first build the new Wal-Mart they encouraged us to park near the building on the wide cement "sidewalk" in front. Then, after a couple of hot months and bikes also parking out in the regular car lot and tearing holes in their brand new asphalt lot, they got a really brilliant idea and came in and made four two parking spaces wide cement parking pads in the four rows immediately in front of the building. These are clearly marked "MOTORCYCLE PARKING ONLY"
Happy ending, Right? Well, only sometimes. Half the time there is a ratty pickup truck or old minivan parked squarely in the center of the new motorcycle parking pad!
Go figure.
