This cache is NOT a park and grab; do not park on Custer Ave, I15, or any of the on/off ramps. See waypoints for suggested parking, exercise caution, and use common sense.
Letterboxing is in many ways similar to geocaching; the main difference is that letterboxes are found by following a series of clues rather than by using provided coordinates. As such, letterboxes are often harder to find than geocaches. Letterboxes also usually contain a stamp. Visit letterboxing.org for more information.
Like a letterbox, this cache has a stamp, but it is at the posted coordinates. Please replace exactly as found and leave the stamp.
I dropped my car off nearby to get a flat repaired, and I had a couple of containers in my pocket that I wanted to place. I was amazed at just how good the view of the mountains is from the bridge here. At points, you have a nearly 360° view of the mountains around Helena. It was this view alone that inspired me to place a cache in an otherwise busy and drab area.
Congrats to Chufra for getting the FTF!
