Visiting the abandoned train tunnels at Donner Summit is a fun and fascinating day trip. When my camera club visited there a couple of weeks ago, we all agreed we wanted to return another day because there was so much more to see. I, for one, moseyed along so slowly I barely made it into the third tunnel before our adventure had to end. This is the second tunnel. My shutter speed was 1/2 second so the people walking through at a faster pace than a mosey are blurred.
