Mr P.
All three Az. tracks have websites with schedules

In Tucson sirace.com
North Phx speedworlddragstrip.com
In Chandler firebirdraceway.com

All three have Summit series races and regular test n tunes and bracket races almost year round. The LODRS is in Tucson in March. Remember MATS in Vegas is a short drive and the Pomona swap meet is March 8th. L.A. is a short drive as also. If you want any directions or tourist info while you are here, I am in southern Az, just drop me a PM.
