We've mentioned that there are various hazards in woods, ticks, falling trees, chainsaw operators, but I think there's one wood in Staffordshire which is in a class of its own. Even if it came on the market for a real bargain, this is one 12 acre wood you don't want to buy. Some 90 people have been killed there, and many of there bodies were never found. Here's a google maps aerial shot, notice anything unusual?

In the top right corner you can just see a small square area on the perimeter, which is a memorial. There's a sign warning you to keep out;
Its a quite deep depression about 300 feet deep, it looks peaceful now but in 1944 it was the site of the most powerful non-nuclear explosion in history, when the RAF bomb dump of Fauld blew up.
Here's an aerial shot just after the big bang, with some further details about the story. There's still tons of unexploded ordnance under the surface. Always useful to check the history of your wood before putting in an offer, or might get a lot of bang for your buck....
