Just got on mapquest and this is what I have:
(I went from Bonsall because thats where im at so take into consideration depending on your location)
Bonsall-Las Cruces 706 miles
Las Cruces-Farmington 405 miles
Farmington-Moab 183 miles
Moab-Phoenix 468 miles
Phoenix-Johnson Valley 306 miles
Johnson Valley-Bonsall 127 miles
so total from Bonsall would be roughly 2195! Thats some serious gas money!
