Fly out of the boundaries of the game in an early stage - taxi missions glitch
In addition to causing the taxi glitch on PCv1, flying off the map can add extra gang turfs, and if both Doherty zones get zone name glitched the Mike Toreno mission can't be completed. Other zone name glitches don't usually break the game but you'll get weird neighborhood names popping up as you drive through town (like San Fierro instead of Garcia).
Flying Skill: I'm not sure if it's been mentioned recently, but the AT-400 isn't chased by the Hydra.
Driving Skill: I've had inconsistent results, but generally a faster car will increase skill faster than a slower car, and driving fast is important. I'm not sure how clean driving influences the skill. Crashing into cars slows the speed but is strangely associated with the popup that skill has just increased.Rare Maps:SA Restricted Areas
Map of 4-star boundaries and military zones. This map accurately shows where CJ can be (swimming is an exception) early in the game without earning a wanted level. It has proved to be very accurate except - the safe passage by boat through that narrow gap north of SF is on the east side of the ship. On the map it looks safer to pass in front of the bow.steve-m's Path Maps
May favorite has the Radar Background
. I found this map useful for finding safe places without foot cops but close enough to a road to lure an Enforcer over for an armor refresh. It should also be useful for avoiding boat cops.Dark52's All-In-One Collection Map

When CJ has a wanted level and enters a Police Trigger Zone
then 1 or 2 cops are spawned. The different trigger numbers will trigger cars or foot cops, but only if CJ is driving or on foot, depending on the type. When PD made this map the police trigger zones were not well defined. At the time we thought that the coordinates that specify where the cops spawn (blue or lines) transcribed a rectangle. Since then we have discovered that these coordinates define a starting point and a direction of travel. So instead of blue rectangles this map should have arrows, but you can probably figure that part out if you know where to look.Vending Machine and Food Cart Map
Hm... It looks like pdescobar's oringal links now lead to a terribly degraded image. Here's an updated

Sometimes it helps to be able to identify a particular zone by name, and I may as well link all of pdescobar's cool maps in one spot.Burglary Homes Map
