What's the road conditions on I-15 south from the 210 thru Temecula to San Diego? I'll be going thru mid day to early afternoon on weekday. Is the 5 an option?
If you can get thru Pasadena before 2:30 PM on a weekday, traffic to the I-15 will be fairly easy. I would recommend even earlier. I'm not too sure how the I-15 is on a weekday afternoon.
