Rails To Trails Logo Draft

I'm on the board of directors for my local Rails-to-Trails organization. We essentially maintain and build new trails on or as close as possible to the over 100 year old railbeds left behind since the old steam engines used to run through the local mountains. We have a logo but really need something different. I'm just trying out some stuff to see what works and what doesn't. Feedback is appreciated and more than welcome!
