Where to play badminton in Sacramento area?

Too sad that there is no badminton club in Sacramento area that you can just walk in and play.
1) Folsom badminton club Location : Folsom Middle School, 500 Blue Ravine Rd, Folsom CA 95630
Time : Sundays, 6pm -9pm
Courts : 8
Fee : $4
Comment : My favourite place to play in Sacramento area, not crowdy.
 
2) Sac State(CSUS) Usually open Friday, Saturday and Sunday night, check out the schedule, it is FREE to public. http://www.geocities.com/Colosseum/Bleachers/2418/

3) UCDavis Here is the info from Tacowall in badminton central(9-2008): The UC Davis Badminton Club will resume practice on Sept. 29 on Mondays and Wednesdays 8-11pm, and Fridays 7-10pm. Club members receive free birds for games. You do not need to be a UCD student to join, however the club is "suppose" to be for UCD affiliates only. Over the years we have had many players from the Sacramento area, and so I have no problem opening the club up to anybody who wishes to join. Hope to see some of you there, just look for me, my name is Will.

4) Davis high school I am not sure if it opens to public. Open Saturday from 4pm to 8pm. The guy's name is Roby and he is nice and welcome people to play there. Drawback: most of players are high school students.

5)Sierra college
Worst place to play. They don't even have lines in the courts.
 
6) Vacaville community center
6 courts, $2 walk in, opens Friday and Saturday night.
