well today at stumptown i was sitting outside with a coffee. had to go in and use the bathroom though, as coffee is a natural laxative anyways my friend was watching my (unlocked) bike while i went. when i get back i sit down and there's this sketchy guy eyeing my bike but i figure he's just checking it out. there was quite a few people around by the way, this is rush hour. then he tries to get on and ride it away so i politely inform him that it's not his bike, and give him a nice punch to the grill. alright minus that last part, i'm not trying to get 86'd from the best coffee shop in portland. anyways post your stories of confrontations with bike thieves.
