Mike or Bob, there is a test track out to the west of Phoenix that I'd like to know about.
I did a Google maps and looked to the west of Hiway 60 on Happy Valley Rd., is that oval track and the associated tracks in use or is that the one that was closed by the neighbors?
Continue looking to the west past the WWII airfield and past the 2nd WWII field on Patton Rd. continue west on Patton Rd. until it ends at the large oval track and facility. Who owns this ? Is it available for private use?
