This is a challenge that is at the posted coordinates. It is a standard magnetic keyholder in a typical location. You can find the cache and sign the log at any point, but you cannot log a find online until you meet the requirements.
Please do not pull over directly at the cache location. Parking is available on the street just next to the cache. You'll find this cache hidden in typical fashion just over the border in Rhode Island from Massachusetts.
For this challenge cache, you must find at least 10 size "large" geocaches.
Rhode Island is the smallest state, so it felt fitting for it to have to have a challenge involving LARGE caches. Those who have not found at least 10 size "large" geocaches cannot log this challenge cache as a find.
