You are looking for a highly visible cache container, maybe not quite the hi vis that we are all being bombarded with, but hi vis all the same.
Once you've located the container you'll need to be very stealthy, this is a busy road - and borders Burnham Military Camp where we live. You'll be highly visible as you retrieve and sign the log book. Loads of people come this way for PT, so keep your eyes open for platoons of soldiers appearing on the other side of the road. You're also highly visible from our house, if you see anyone at the first house on the road (the one with the purple and green playhouse) wave out. The cache has two containers, one for swag (gold) and one for the log and stamp (blue). You are highly visible, STEALTH REQUIRED.
This cache is placed with the permission of the Camp Commander, so there should be no trouble with security, however there are still plenty of military muggles about.
