I did a very quick and dirty look at the following for G04- DPL, SCDSL Discovery, SCDSL Champions, Coast Premier, Coast Gold and SDDA F1.
Here is the breakdown by rough geography when you combine all of these "Top" leagues (I omitted 2 teams from Coast because I couldn't figure out where they were located)
- East - 11 Teams (including Temecula area. I suppose Temecula could be included in San Diego)
- Los Angeles - 9 Teams (Long Beach to Downtown)
- North LA/Valley - 8 Teams (Thousand Oaks up to Santa Barbara)
- OC - 9 Teams (South OC to Cerritos) 4 of these 9 wear some form of a Slammers patch.
- San Diego - 11 Teams (Could have North SD play with OC )
So all of this talk about "You need to travel more if you are in a higher flight" might not require as much travel as people think. Sure, teams in North of LA and in areas like Santee, Lakeside would have to travel. But for 80% of the teams, you can probably find good competition within 30 miles- Even at the F1 level.
This does not include DA or ECNL teams.
