I was lucky enough that the conference I had to attend (which changes cities every year) was in Pittsburgh the year I gave a seminar! I really enjoyed riding the bus downtown to the Convention Center everyday, and the venue is really beautiful. Located right on the river, the balcony views from the upper tiers of the center are pretty fantastic. Furthermore, the maze inside was pretty easily navigable- this was really important to me because I had to get in and out of rooms quickly as seminars started and stopped every 20 minutes. Compared to other venues I've been to across the country, the David L. Lawrence Convention Center stacks up well. It was great to see Pittsburgh showcased in such a great light.
