Hey Now!
Thanks for re-posting your trip report. AWESOME read!!!
Discount Tires is the best. I've been dealing with them for years and they EXCEL in customer service. If you're ever at GVR and need a gas station, turn right onto Green Valley Parkway and go about a mile. There's a Chevron Station located at GV Parkway and the first major intersection. Sorry, I don't remember the name of that street. That road will take you to Eastern if you need to get back on the 215 or to the Parkway that goes to M Resort.
Congratulations on a fun successful trip.
