This cache is in a very old, abandoned railroad tunnel along Hwy 24, that goes NW from Colorado Springs to Woodland Park, Colorado. Bicyclists sometimes ride along Hwy 24, but not too often. Photos attached -- the old railroad trace is now a trail, so there are probably mountain bikers that go along here, but certainly no cars ! Photo 1857 is looking down onto Hwy 24 from the cache location, just outside the south entrance to the tunnel. Sorry the coin is hard to see in photo 1860; I tried and tried, but couldn't get a clear photo of both the coin and the tunnel.
