Killer 3 day weekend trip would be to head out say on a friday night. Get a room in Prescott, get some drinks and party a bit on Whiskey row. Hit up someplace down town for breakfast and hit the road at a reasonable time sat morning. Head north on 89 to Chino Valley stopping at the Dells for pictures and to check out that area. In Chino take perkinsville road to Jerome. I've got GPS, it's a fun dirt road. You won't use 4wd at all and a car could make the trip but I'd definitely want a truck with aired down tires. Get into Jerome early afternoon Sat. Spend the afternoon screwing around in the gold king mine ghost town. Hit up Jerome the town for the evening bar hoping thru the saloons and get a room in Jerome. Sunday morning grab breakfast in Jerome, hit up whatever random tourist gift shops and then head to Sedona. In Sedona do the broken arrow trail in your jeep and then take Schnebly Hill Rd over to I17 which is a dirt road that's got endless amazing scenery. Hit the I17 and head south down to Montezuma Castle. Check that out and then head back to Sedona late afternoon to do the touristy thing, bar hop, then crash there sunday night. Monday, head north up 89A to Flagstaff, have lunch or whatever there and then hit the road back to Vegas...
That right there would be a pretty *****in way to do a 3 day weekend out of town. Especially if it was say early or late summer when the temps are actually pretty nice there but getting toasty here!
