Took my decompression route home and was riding along, behind a bicyclist, coming up to the curvy area. Then about 5 bicyclists popped up around the bend going the other way. Instead of passing the one on my side (he was behind the shoulder line, I had plenty of space), I decided to sit back and wait... Good decision, a pick up truck driver decided that a blind corner is an EXCELLENT spot to pass 5 bicycles by straddling the 2 yellow lines... If I had gone to pass, I would have been right there... It's good to have that 6th sense, isn't it!
