On 4/30/07 I was told by someone who lives in the area that this road had been repaved, but I have not been able to verify the limits of new pavement.

Old San Marcos. Rd. was the old way up the mountain before they built the 154, and I mean UP the mountain. If you are looking for a place to drive fast, look elsewhere. This is a low speed, very technical road, where you will probably not get out of second gear.

This is not a well maintained road. There are signs at the bottom warning you to look for washouts. There is no line down the middle, and most of the upper section (blue on map) it isn't wide enough for two cars to pass each other.

This road has been around a long time. It inspired some driving enthusiasts to start their own car club in the 50's. While there are enough people living on the lower section (red on map) to make it real fun, there are some switch-back u-turns on this road you just have to drive to believe. The upper photo shows them in plan view, but there is so much elevation change that you are lucky if all 4 tires stay on the ground.

It is a little easier to get some speed up on the upper section as there is less traffic and the road surface isn't quite so poor, but you still need to be on the lookout for motorists and bicyclist coming down the mountain.
