About 200 bicyclists on Wednesday evening went on a group ride to honor Alan Grahn, 75, a Minneapolis cyclist who was struck by a school bus and killed at Snelling and Summit avenues in St. Paul on May 9.

The riders gathered in a Grand Avenue parking lot, then moved slowly on Summit to the collision site, where a painted-white “ghost bike” has been set up as a semi-permanent remembrance and cautionary message.

After a period of grieving and introspection, the bicycle group continued westward to a St. Paul rock-climbing club where Grahn was a regular.

The fatal crash remains under investigation by St. Paul police.
