The cache is hidden on the wooden bridge that crosses Prairie Creek. The creek is typically dry, do not attempt if the creek is flooded. You are looking for a preform bottle. (Bring your own pen). You may need to rely on your geocaching senses to make the find. Another tough bridge cache is just down the trail; GC6GK2Z "Stray Cat Blues".
Take time to explore the area. The city of Rogers is making a lot of improvements to the trails and parks. Nearby you will find a dog park and pavilion. The paved trail travels north towards Lake Atalanta and connects to trails going west towards the Railyard (BMX bike park) and downtown Rogers.
The title of the cache may also help with your Alpha-Numeric challenge.
