It can get hilarious sometimes! I recently was in SAN on business and was supposed to meet my new client at his golf club - Marbella Golf and Country Club - close to San Juan Capistrano - yahoo maps was doing great until I realized I was at the end of the directions but was in downtown SJC. I may be confused about many things, but I knew right away there wasn't a golf course downtown

After calling the club, I was a good 6 miles away. Apparently, the map software took me to the closest downtown for the zip code I entered.
Fortunately, I made the tee time, but barely! The golf, on the other hand, was anything but successful - KILLER course!
