Today sounded like it ought to be an easy day after several days of the traffic on I-5 in San Diego. It was only 103 miles inland and camp was to be below 1000 ft. elevation. But, after we left Del Mar and the Interstates we started climbing. Then we came to a sign “RV’s over 40 ft Prohibited and not recommended for trucks with trailers over 30 ft.” So what does that mean for a 33 ft RV pulling a 29 ft trailer? Apparently what it means you are going to be seeing your own tail lights on some of the switchbacks. After we climbed through that stretch of road we came upon another sign that repeated the prohibition but it was just past our turn-off, no problem. Then, later we came to another set of signs and another turn. Still no problem. Then we came to the HILL. We dropped 3,000+ ft of elevation in the last 10 miles getting to the campground that is indeed around 700 ft elevation. 10 miles of switchbacks and road marked at 8% downgrade. It took some patience (mine and other drivers) and a few mils off the brake linings to get down. Second gear was not sufficient to hold back the rig without braking a lot and I even resorted to First for a while on the curliest/steepest part. Thankfully our next destination is just down another 900 feet or so in elevation and about 15 miles west of here. Should be a breeze. If you questioned the math, give yourself a pat on the back for attentive reading. Yes, the next stop is at elevation -227 ft (below sea level).
