Yes, US, late 30’s.

I’ve seen many Bison Tubes sold online, small Tupperware containers that have a locking lid, even peanut butter jars covered in camo tape are somewhat common. The best ones are custom made. Some great ones are 3D printed to fit in (think oversized acorn in a tree). I also enjoy everyday objects that are out of place like a pop up sprinkler head placed in the ground with the log inside. I made one that was a log where I bored out the middle. Those hide a key fake rocks work nicely as well.

Shorts in 10C is standard practice for me. Really not that cold for us in the NorthWest. Now if we’re talking Southern Californians 10C is heavy winter jacket weather.
