Spelunking to Devil's Den Mountain

Hi, come out for an adventure as we go "spelunking" (cave exploring) to Devil's Den Cave in New Durham. This is a three hour hike. We will be having lunch on top of the mountain after we go through the cave. Please bring appropriate footwear and a head light.
Please do not be afraid of the "dark or confined spaces". You can come along just for the hike and not into the cave. Your choice.
We will be meeting at McDonalds at the Alton Traffic Circle in Alton NH. And carpooling to the base of the mountain.
Please arrive early as nobody likes to wait for others. We will leave from McDonalds at 11:15 am so make sure your here by then.
See you there!
Pete
