I found a cache similar to this one when I was just starting out - been looking for the right spot to place my own and voila! I've primed it with a couple of TB's that need to move along. It's big enought to leave a few small trinkets if you please. The rules say no tea or crumpets.
Parking is easy in this neighborhood but be on the lookout for the Red Queens Armoured Cards (muggles) - there are lots of neighbors who run and walk their dogs as well as a healthy neighborhood watch. Make like the White Rabbit and be quick about it!
