You are looking for a magnetic nano.
Please use the stairs that the nice trail maintenance crew provided to get to the cache. It is a friendlier way for you and the trail bank. Groping behind I beams is not required.
The log sheet must be signed or your log will be deleted. None of this touch free caching bs.
The rail trail surface is pea gravel and is suitable for bikes and strollers in the non-snow months and is available for snowmobiles with a permit in the winter months.
We suggest you start this series of caches from CTA Nearby Parking ( GC55XJH ) to avoid encountering the No Parking signs at 14th Line.
