The cache is a regular sized container. The log book is in the container, but probably won't be in the first place that you look. Once you sign the log book, please replace the contents of the cache as you found them. This cache is not recommended for trading items.
There is one main path into the baseball diamonds, which I have marked the trail head for. You could access the cache from other directions, but it will be quite swampy as German Mills Creek flows through.
You cannot park on Bayview Avenue, but there is parking on Bantry avenue or the plaza on the east side of Bayview.
