SD is all transplants. I have family in Encinitas and they aren't Charger fans. I went to a Pats-Bolts SNF game 2 years ago and over 50% of the crowd was Pats fans. Raider and Broncos fans regularly take over the SD stadium as well. SD doesn't really support that team and LA is only 90 miles up the road. Traffic probably adds an hour. I don't think LA will support them more but the team originally was founded by Paris Hilton's grandfather as the LA Chargers.
