Depending upon your rig setup and availability there are a few choices in Aug.
Pismo Aug 4-6 (Note: you cannot stay overnight legally now as this weekend is already booked out, but you could do a day run)
Sherman Pass Aug 11-13 (Need sliders, AT or better wheels, recovery gear)
Big Bear Aug 19-20 (3 run groups for all setups and abilities)
Cheers
