There is a new complex in San Jose that is finished but hasn't opened (Arcadia complex)
You couldn't pay me to play in Antioch, Martinez or Concord these days. Never liked any of those complexes.
Mr. E: As you were coming up I was winding down my travel days. I played in all those early birds from the early 2000's to the early 2010's and called it a day in 2012 with the exception of some 40s, Nutters, Backyard boogies here and there.
There is a new generation of players though, so you may be right with potential growth since they don't know the history of what has gone on and that is a good thing.
As for complexes to play in the area we are stuck with the Fremonts, P-Towns, East Bay , Manteca's, Sacramento's, etc...
Ripon mixes some in, even Dublin too... too bad Redwood City doesn't do anything or San Mateo...
Played some great tourneys back in the day in Palo Alto (Across from Stanford) and Greer Park in PA, even mixed a few in South City 35+ years ago.. Oh forgot Critteden park in MV was solid too for years
