Poetry Thursday this week asks us to think about and even participate in Guerilla Poetry! That is to print or write out our own poetry and leave it in public places for other people to find. This sounds remarkably like Bookcrossing, where people register books with the site and then send them to other members or leave them in public places. If I send a poetry book to another bookcrosser, I always include some of my own poetry inside, in the form of a poetry card or a small flier of my haiku. I also try to remember to do this if I'm leaving a poetry book in a public place. I recently left a book of poetry by the statue of the Edinburgh poet Fergusson, which has now (the book, not the statue!) found its way to Canada! I have sent poetry books to Spain, Germany, Australia and Netherlands. Some of the books have then been left in public places in those countries.
When I give poetry readings, I generally leave some of my poetry on the tables in the venue. I always carry some poetry with me to give to people I meet who are interested.
As for just leaving my poems by themselves in public places, I haven't done that yet, though every year I imagine myself wandering down Edinburgh's Royal Mile, giving fliers of my poetry to passing tourists during the Festivals. If I dressed up as a giant rabbit, it would probably be easier (If you've ever walked down Edinburgh's Royal Mile during the Festivals, you'll understand why!).
A good site to visit for ideas about Guerilla Poetry is Random Acts of Poetry.
