City Living

I have officially been a resident of the city of Saint Louis for almost eight months now, and I've learned that there are some unwritten rules for living here.

1.) Good fences definitely make good neighbors, so if you have a fence (and if you live in the city, you probably do), keep the weeds trimmed on your side.
2.) The alley isn't your personal space. If you have a grassy plot adjacent to the alley, sure, use it for whatever, but don't park your vehicle right in the middle of the alley.
3.) Also, don't walk down the alley. There are plenty of sidewalks to use. Also, walking down the alley riles up all the dogs on any given block.
4.) Many homes in the city have garages. Many more don't. For those homes without garages or driveways, street parking is the only other option. When you and your neighbors have to park on the street, the unwritten rule is that the area directly in front of your house is yours. Sure, I realize this is not enforceable in any court of law, but 99% of the time everyone will abide by this. It is easy to spot the newcomers to any street because they will, more often than not, park in front of two houses at once.
5.) It is good to know the people who live in front of, behind, and to the sides of your house. They will look out for your interests and you will look out for theirs because they are one in the same.
6.) If you live on a side street (like me -- Pennsylvania Avenue) don't hold your breath waiting for a snow plow. It will never come. The city says it will, but it is best to operate under the assumption that the city only has one snow plow. While city employees may not technically be lying when they say that your street will get plowed eventually, what they omit from this statement is that by the time "eventually" rolls around, it is July.
7.) Don't be afraid to dial 911 if something seems sketchy. Sure, you can call the police department's non-emergency numbers, but they're just going to tell you to hang up and dial 911.
8.) If you're hosting a party, barbecue, seance, or AA meeting at your house, inform your neighbors so they know that there will be a few extra cars parked on your street, but that it won't be a long-term thing. Nothing sucks more than to leave to get some groceries only to come back and find that some stranger from the county has parked midway between your house and your neighbor's house, making it impossible for any other vehicles to fit there, and then having to walk around the block with five bags of produce and frozen food.
9.) For the love of all things holy, don't try to make a U-turn in the middle of a block on a side street. Just go down to the next intersection and turn around there.
10.) If you're going to have some sort of outdoor gathering in your back yard, invite your neighbors. That way, they can't complain about the noise, since A) they knew about the party in advance, or B) they'll be there having a good time.

Do any of my fellow city-dwellers have anything to add? Specifically, I'm looking for St. Louis city dwellers, but if there are any opinions from other areas (NYC and Chicago friends, I'm looking at you), I'd love to hear your tips, too.
