GeoPoemCaching

from Stephen Vincent, POETICS LISTSERV, BUFFALO.EDU "Geocaching, an online game in which players use global positioning devices to track down hidden containers at coordinates posted on a Web site, is soaring in popularity" Has anybody or group been doing with poems?  I think it would be an interesting challenge/adventure to "cache" poems in tins or boxes - either new or classic ones -  in environments that relate to the poem's contents. Say, different  Wordsworth poems at various, appropriate GPS sites through the Lake District. Frank O'Hara poems on x GPS Manhattan sites. A particular parking plot for Spicer's poem in relationship to  Robinson Jeffers.  New poems written on and in response to particular sites. (David Chirot writes a poem at x GPS location and Milwaukee poets go on the search!)   Found texts are then scanned, and the sites are photographed with a focus on the facts relate to the poem and then transmitted back to the host site (Class, online mag or what/where ever.).  I do wonder if anybody is doing this already????
