It is best to park a little back from GZ, towards the Mendon direction side. You can easily walk to GZ and you will be looking for a bison container. It is not in the trees, it is not "under' the boulders. Millville, yes I remember this town. I never thought I would get this town, for the MA 351 challenge, as it, at least I feel, a rather challenging town to cache in. Again please watch out for poison Ivy. Congrats to ~Marvalus on FTF! Happy Caching!
