Grapevine?

Well, we did it! We chugged up the Grapevine grade with no problem. Vehicle temps were fine and we didn't go below 45 MPH. It was very windy and cool and this may have helped. For those who don't know, the Grapevine Grade starts at 450ft above sea level and peaks at 4144ft. All this in only about 6 miles! When its hot, there are cars and trucks pulled to the side overheating or actually on fire. Now, we literally have a straight shot up Interstate 5 to Highway 4 and home.
