Just a "Thank You" cache for Georick402 and Chloe52612. Also it commemorates perhaps the one section of trail in Montgomery County that doesn't currently have a Georick402 cache on it. 
PLEASE place the cache back with the bison tube side DOWN so that water does not collect in the log holder and the cache is less obvious.
The closest trailhead coordinates are posted but this cache is reachable from other trailheads and trails in Rock Creek Park. Parking in the evenings and weekends should be easy but business hours could be tricky. Please note that most of the surface lot and garage parking is private. Street parking is paid Monday - Friday, 7am - 7pm.
Bison tube hidden in a larger host. DO NOT attempt to pull the bison tube out. Just UNSCREW the cap to retrieve the log. Log only, no pen so please bring one. These kind of caches are usually pretty annoying but don't fret, the hint should make it pretty easy to find. Cache is placed such that you shouldn't need to scramble around on a lot of rocks or go down any steep embankments... if you do you are likely looking in the wrong spot. GPS bounce can be pretty bad in Rock Creek Park so if need be, use the hint.
NOTE: November 2022 - we are moving the cache back closer to its original location making the difficulty a bit higher.
