During the summer, the speed limit through this section of 29th (bordering Manito park) is changed from 30mph down to 20mph due to increased pedestrian traffic during the warmer season (especially since there is a pool there). Anyways, throughout the summer months, I see motorcycle cops sitting just inside the stone alcove in the center of the park. It’s impossible to see them until you actually pass them, and they are there quite regularly.
