I used 101/202 for the western sites because that's what you used for your second distance, the difference to the west from 101-I17 & the Stack is only a few miles, so I figured you were trying to give East valley residents a benchmark. The 25 miles was the difference to the site from I17/101 between the Clint's well route & Stoneman Lake Rd, not just to Lake Mary Road. I agree that the reduced speed and wear & tear on the vehicle isn't worth the miles saved. Who needs streets & trips if you've got a post it note? Heck we do that at work to get mileages in places like Malaysia and we're a multi billion dollar company.

Why then the 101/202? :-) The difference is 14mi, which is the 101/I-17. The 101/202 is closer to I-10/I-17 (by only 3/4 of a mile). > Here's what I got from Streets & Trips, which jibes with my driving > experience to the following sites (except antennas, which I've yet to > get > to): > > 5 Mile Meadow: from I17/I10: 147mi (Via Clints Well) > from 101/I17: 134mi (via Clints Well) Wow, I was only off my 3 miles by using the edge of a post-it note. > Cherry Road: From I17/I10: 84mi > From 101/I17: 70 mi > > Flatiron: From I17/I10: 57mi > From 101/202: 71mi > > Sentinel: From I17/I10: 98mi > From 101/202: 112mi > > Antennas: From I17/I10: 92mi > From 101/202: 106mi > I'd definitely advise NOT to take Stoneman lake road to 5MM.

Were you instead measuring kilometers? The distance of 147 miles now saves 11 miles. How did you manage to save 35? A straight-line drive from Camp Verde? No wonder it was so rough :-) I-17 106 mi 106 Stoneman Lake Rd 16 mi 6 Lake Mary Rd 9 mi FR-229 5 mi 15 total 136 mi 127 (4x4 only and very lucky) Doing some math, if you'd take Stoneman Lake Rd and want to arrive at 5MM in the same amount of time as via Clints Well, you'd have to drive the Stoneman Lake Rd segment at 32 MPH if the entire Clints Well route were 65 MPH, or 25 MPH if the other was entirely 55 MPH. These speeds are probably still too fast for a washboard road. Stoneman Lake Rd is not worth it. If road conditions do not allow an average speed of at least 28 MPH, it will take longer than going through Clints Well. -Paul
