Zoobomb

[1] Participants carry their bikes on MAX Light Rail to the Washington Park station next to the Oregon Zoo.

[citation needed] The event is treated in a very lighthearted fashion, including a large amount of socializing between rides.

Zoobomb tries to be a positive force in the community by providing a safe environment[citation needed] to have a good time and to support bicycle advocacy and alternative non-polluting transportation.

There are several annual events hosted by Zoobomb organizers and participants, including: Zoobomb has inspired Hoodbomb, where participants gather at the Timberline Lodge and bomb the 5.5-mile (8.9 km) course of Timberline Road on Mount Hood.
