About the Container
You are looking for a colorful plastic thermos. There is room for trade items and travel bugs.
About the Location
You will need to walk to this cache on the trails that run parallel to the river. The nearest parking is at Riverside Park to the north or Caesar Park to the south.
The container is hidden about half way up the hill. The terrain isn't too difficult, but use a regular amount of caution. The hill will be slippery if the conditions are muddy or icy. Plants or freshly fallen leaves could hide loose stones or other things to trip over. It will not be a good cache to find if there is more than an inch of snow on the ground.
Passersby will be able to see you from the trail, so some stealth may be required. As always, should you be caught, the Secretary will disavow any knowledge of your actions.
