The President of the London Centre of the Royal Astronomical Society of Canada (RASC) is a cacher and maintains 2 caches at the London dark sky site. It's in the Fingal Wildlife Conservation Area, west of St. Thomas, Ontario.
One of the caches is called Mini Me (I think). I forget the other. Search for user, 'Astronomizer'. He may be interested in participating in something.
I play with an 8 inch dob and a pair of 20x80 binocs in my backyard. Might be fun to do a caching/observing event.
