Someone sent me an email inviting me to one of the local scifi meetups, http://scifi.meetup.com/31/boards/ there might be one in your area. It was great fun:)
Note: The comment above was written afer I read Sean’s blog entry saying that he took sci fi books he didn’t want anymore and traded for some he did at a big sci fi dinner. That sounded like fun to me and I asked him how he found the group.
I’m a big sci fi (and fantasy) reader.
