yes for thursdays and other days.
no for the silly card.
as for silly cards, the IMSA has gone under apparently. to ride elsinore you need their own card. to ride Starwest you now need the AARA card- if you have an old IMSA card, you get the AARA card for $15, if you dont then its $30
the whole thing is a big rip off- you pay these stupid fees so they can buy insurance through this broker- its the same insurance that Glen Helen buy direct and you dont need a card there!
Me, if i ride the in the week, i go to Cahuilla and saturdays is racing at the back REM track at Glen Helen.
F- starwest and elsinore- those places are dumps anyhow and you have to avoid all the kooks as well.
