In most song structure (verse, chorus, bridge) the bridge is where the song changes dramaticaly in form, rhythm, tune, etc. At this bridge, this Thun hide is a change too. Look for something just a little different than you have found along here so far. Keeping it interesting.
Note: The Thun Trail (pronounced tune) is part of the Schuylkill River Trail System. This cache was placed as part of a series that KilllerBee and Trekker67 (aka KBT67) are hiding along the trail to hopefully encourage geocachers to travel this route.
Happy Trails!
Congrats to Rentell for FTF!
