TNLN, I Don't Think So - 1960's Traditional Geocache

My TNLN series continues with what should be a really fun cache to find (more for me than you).  I placed this cache in a location where I use to play as a kid.  This was my first time back in 25 years.  For those of you that use mapping software to find streets and directions to get to caches, you'll be surprised when you see the location of this one.  It really is there.  There are many ways to get to this one.    The cache container is an altoids tin large enough for some log sheets and small trade items if you want.

   1.  Inside the cache is a coin dated from the 1960's. Just replace the coin of a different denomination dated from the 1960's.

   2.  When posting your find, just list the denomination of the coin you left and took.

Failure to follow both rules above will mean that I will delete your log and you won't get credit for the find. 

That's it, sounds pretty simple, doesn't it?  Here is a little hint that I won't even encrypt.  Don't attempt this one during or soon after a storm. Also, you might want to bring a flashlight along regardless of the time of day you attempt this one.
