re: #85 calochortus

They have some that size around here, but they function as “traffic calming devices” in residential neighborhoods and aren’t on streets with a lot of traffic. You just have to be at or just below the speed limit to negotiate them successfully.

In Cheyenne they are putting them at Interstate off-ramps, and just finished a five-street roundabout near the VA Hospital that is an absolute disaster (two major streets plus a third minor street, the roundabout is about the size of a half-dollar).
