For those of you who are planning to drive while in San Diego, should know that it is now a law--with a heavy fine--that you must not pass a stopped school bus, that has red lights flashing, from either side of the road.
In the past, you were only required to stop behind any school bus letting off children (red lights flashing.) Now you must stop even if you are on the opposite side of the road, as well. It doesn't actually happen too often unless you're driving near schools or in residentila areas most of the time, but important to know so you can avoid an unpleasant encounter with local law enforcement.
I bring this up because I don't know the proceedure under these situations, in other countries and you might not know about ours.
While driving in San Diego, and encountering any emergency vehicle--police, fire engine, or ambulance--with it's lights flashing/sirens blaring, you must pull over towards the right, in a safe manner, and stop until it has passed your car, to insure safe passage for the emergency vehicle and for you.
Failing to pull over and stoping, can result in a traffic ticket with a heavy fine.
Unless your dog is a service dog it is against the law to have your four legged companion with you(EVEN ON LEASH) at Clairemont town square. EVEN THOUGH there is a petco in the square. The security said "You MIGHT be able to get away with having your dog in front of Petco...MIGHT." so yes, you'll most likely see dogs there but if security isnt having a good day and you have your furry litte friend with you, you guys will have to leave. It happened to me and my husband.
Be warned about having your car towed from a parking lot. Most parking lots display a warning sign that says that your car is subject to being towed if you leave the parking lot. They are serious! This is not a town where you can park your car in a shopping center parking lot and leave the premises. I did so - to look for an ATM. I was gone for about 30 minutes and returned to find my car missing. It had been towed. The cost - a heft $280 (payable either by cash or MC/Visa) to be able to get my car returned. Not to mention the $20 cab ride to get to the location.
Check the parking lot you park in for signs. Apparantly the security firms are watching quite closely.
Legal drinking age in California is 21 - what a difference with Europe (18).
Never try to buy any boose when you are under 21. Even if you are above but look younger you will be asked to show your identity. I saw a warning sign in a liquor story that each customer under 30yo maybe asked to show his/her identity. Unfortunately they didn't want me to show them my identity hehe!
And it seems that they are very strict about it. I saw a guy who for me looked not so young, 25yo or so but I saw him showing his identity to the cashier in a supermarket - they communicated in Spanish.
But when you are in San Diego and you are 18-21 you can get a trolley to San Isidro (blue line - last stop) and walk a few hundred yards (meters) across the border (NO control in THIS direction hehe) to Tijuana. Legal drinking age in Mexico is 18.
Warning: coming back you must wait in a very long line (1/2 mile or so) but it goes smoothly - I waited approx. 30 min.
You read the sign, you get the idea. Messing with the animals at the zoo isn't good for them and it might get you thrown out of the park.
