First off, the no-brainer safety rules: DO NOT PARK ON THE BRIDGE, DO NOT ENTER THE ROADWAY! A waypoint has been added for parking, and the cache is not in the roadway.
This is a quick find on the pedestrian walkway on Garrison Rd Bridge and the location offers a nice view of the Arkansas River. It is a bridge, so if you drop anything (including the cache), it will be gone, so be careful.
Congrats to Yazz for a FTF! I think it may have been his first ;)
