O N L I N E . . . .
not only can you hike out into the woods,
As with most things, a version of letterboxing has recently moved online. After a few girls on an art list I'm on had mentioned wanting to know more about it (and had no boxes in their immediate area), I whipped up what I believe to be the first Virtual Letterbox, and posted it.
Within minutes, there were more than a thousand hits, and as the link spread, well...let's just say that my servers were pretty busy for awhile.
Luckily, no good thing has to be a one-time event online, and others have begun making some virtual boxes, as well! If you'd like to try your hand at a letterbox, try one of the ones below, or see the main letterboxing site for clues in your area!
