a lot of that griping you direct the forum to at cascade are gripings about temporary sharrow treatments, catgirl.
I ride all over the city and see more good sharrow placements than poor. I'll going to ride 45th just for the heck of it (rode it this week to the cobbler's) and will take pictures. Should I loop out to West Seattle? last time i rode it things felt same as it ever-was still very bikeable.
Sharrows on Dravus across 15th,
Connecting greenlake and rooseveldt at 72nd,
uphill on 10th, 19th on capitol hill,
North of the university bridge on the clusterfuzzles there,
the stone way cooridor,
ballard between fred meyer and old town ballard,
and many more...
streets with a mix of bike lanes and sharrows, and intersection treatments all across town, and others all over town vastly outweigh the poor placements IMO..
