Located in what will be the NEW downtown Markham development with just about everything you could possibly need (soon). The construction started about 2010 and I don't know if it will ever be finished... When we first moved to the area in 1980 we were almost in the middle of a corn field, this is quite a change for the area.
The cache is a small magnetic key holder containing just a log sheet, so bring a writing instrument to make your mark.
Congratulations to 69Maverick for the FTF
