Rothrock Tunnel

We were running around the Rothrock State Forest area doing a little biking and hiking and we run smack dab into this awesome tunnel.  When one looks at this picture you invision the smaller opening to be quite small, more like for drainage.  In reality, you can easily sit or stand on your bike and pedal easily through this opening.  The other side of the tunnel is rather crude in comparison but awesome just the same.  This was definitely a "whoda' thunk" moment.
