Vancouver seems to be the Hitchhikery place at the moment, with all sorts of events around the fact that The Hitchhiker's Guide to the Galaxy is the choice this year for the whole city book club organised by Vancouver Public Library.
Hitchhiker's won in a public vote over the other two shortlisted books: The Absolutely True Diary of a Part-Time Indian by Sherman Alexie and The Adventures of Sherlock Holmes by Sir Arthur Conan Doyle
Events include a radio station broadcasting the first six episodes of the radio series, and something called a "Vogon Poetry Slam & Vog-Off". Plus others less Hitchhiker related included select items for a time capsule.
