SCPOC Caravan Spots
Below is the caravan meeting place for the Los Angeles/Orange County members. Credit goes to Robert Enloe for the drawing (and the directions, since it was taken from his website).

Directions:
Exit the 55 freeway at the Katella
off ramp,
and head East on Katella.
When you exit the freeway onto Katella get in the left hand lane.
Before you get to Tustin Ave. there will be a left hand turn lane before the light at
Tustin, TURN HERE!
You will be turning into the PetLand (or Pet Co.) Parking Lot. This isn't a problem, just
drive through it and go park at Wendy's (address is below, in case you would
rather use MapQuest).
Wendy's Old Fashioned Hamburgers
1237 N. Tustin Ave.
Orange, CA 92867
If you screw up, and don't turn into the PetLand parking lot, just make a U turn at the Tustin stop light and turn into the first driveway on the right-hand side. then you will be in the PetLand parking lot!
Below is the designated meeting spot for the San Diego crowd:

Directions:
From the 15 North, exit Aero Drive and turn left. From there proceed west to Ruffin Rd. and turn left again.
From the 15 South, exit Aero Drive and turn right. Go west to Ruffin Rd. (the first stop light) and turn left.
Go down the hill and continue past the shopping center until you reach Stonecrest Blvd. and turn right. By this time you should see the Fry's Electronics. Turn left into the parking lot. In the parking lot, go to the side that faces the freeway and you should see all the Probes (unless you're the first one there).
Here is the full address for Fry's Electronics in San Diego (to help with MapQuest searches):
