My vote's for Calgary.  Must be a hoard of Jim fans here judging by how long I had to wait in the 'reserve' queue in our local library system to get to read 'Changes', and they had 18 copies in circulation.  Yes, of course I'm going to buy it, but I don't generally buy hardbacks because of space constraints - we have 4 adults in our house, all of whom are voracious bookbuyers - it's a matter of survival.
How about coming to 'Con-version' next August?
