OCC,
On the first leg of the trip it was 55-65mph until the climb to Yarnell probably 40 miles. Then it was pretty slow going due to switchbacks etc so probably 30 miles of <35 miles per hour. In town it is 30 MPH on back roads, 45 on the highway so maybe 30 miles of a mixture of the two. Then back was 65-75 with a lot of drafting of a semi total of 90 miles. At the end about 5 miles of 35-40 to get home. If we take the freeway on the uphill and go 75 when possible 65 through the steep part, we only get about 27-28 MPG for that leg. Still not bad for continuous uphill at a pretty good speed with the air conditioner on.
