A park and grab beside a rarely read roadside history sign that most folks sail right past. Rather a small pullout to park at. Log only. (Actually there are 8 historic signs on site, according to an on-line resource I just checked. Several can be spotted from the pullout by the road.)
*** Be aware of traffic on the highway that does not slow down at this point. While finding the cache, and when pulling back out onto the roadway. ***
Congratulations to Danero1919 for being the FTF this geocache.
