I don't want to hear anybody arguing about bike lanes now. The Sharrows are here and the bike lanes are yesterday's news baby. One thing I haven't seen but will be glad when I do is removal of existing bike lanes for sharrow treatment.
Agreed that placement is critical. Denver seems to be about 70% good with these new sharrows. The old ones were just about useless.
One thing I'd like to see is mini-sharrows in the middle of left-turn-only lanes.
