This series are all winter friendly caches and you'll need to bring your own pen.
Cache series hidden along a nice hiking and biking trail in Charters Settlement.
The cache containers are big however the actual size of tradeable holding space is very limited so small trades only.
This light fixture slides into a groove on Artillery pieces to illuminate the reticle to allow the artilleryman to see the graticules on the reticle. 2 D Cell batteries and a turn of the switch and the target is illuminated, so to speak. The Royal Canadian Artillery- changing the landscape: one grid square at a time.
