"Letterboxing is an old English pastime combining orienteering and treasure-hunting skills with craftsmanship and inventiveness ... Traditionally, this is a nice countryside rambling activity. Now we're going to do it in the city" -- Urban Letterboxing [thanks Warren]. (Some friends and I tried the dead letter drop idea round London a while back. It's harder than you'd think to find a good place.)
