To make way for a hyperspace bypass, of course. As mentioned here, Hitchhiker's Guide to the Galaxy is coming this Friday. Chris Sells has posted a note inviting any and all to the viewing at 7:35pm at the Regal Evergreen Theater in Hillsboro, Oregon.
I've seen various reviews all over the place. As pointed to here and here, there doesn't appear to be a consensus over the quality of the movie, but as Chris says, "I am really excited about this movie. I love the book and want badly for the movie to be an excellent alternate way for me to enjoy the Hitchhiker's universe." Bravo!
Come on out and join the gang.
