UPDATED APRIL 11 2018: Container was still there and still dry but was hard to open, so replaced with something different. And since a nice new boardwalk has conveniently appeared since 2016, I moved the cache to somewhere a bit higher and drier.
Visited Guelph today and took the opportunity to fulfill a cache request. I intended to place this in a different section of the Arboretum but this spot spoke up and I couldn't say no. I may move it next time I visit. Or maybe I'll just hide another one.
The container is a 500 mL plastic bottle. Contains a logbook and swag including a few nice custim made magnets courtesy of Lone.R. There's room for trade-items.
I spent a lot of time in the Arbouretum when I lived in Guelph. It's a great place, especially for a nerd like me who likes to know the names of the trees. I would spend hours wandering around, looking at trees and reading those names.
That was before I learned about geocaching. Now I wander around finding stuff that others hid.
