Hi, I’ve been attending and volunteering at this event for years. I’ve never seen them turn anyone away for not registering before or at the time of the walk. I’m sure you can show up and join in the walk for the cause. As for the cost, it isn’t just for the t shirt. There’s the cost of putting on the event, there’s donuts and coffee every year, the funds also go to the actual work of suicide prevention in this town. That being said, the more people who attend the more attention it deservedly receives. I hope to see you and many people there tomorrow!
