Replace Mark's Tires

On October 22nd Mark Holzmann wrongly cut off someone riding a bike. That night the person who he cut off disturbingly found where he lived and sliced his tires leaving a threatening note.

The world is full of too much aggression right now. Let's show Mark that the Portland bicycling community stands by him and rejects the actions of the very angry person who slashed his tires. 

Here is Mark's account of what happened: https://www.oregonlive.com/opinion/index.ssf/2018/10/post_219.html
