It turned out that we had a full group of people (five) last Wednesday to play Ticket to Ride at work. We didn't quite get a full game in as we ran out of time, so we had to call it a little early.
I brought it in again today at someone's request, and we played in the main break room. There seemed to be quite an interest in the game and a few people watched for a while. And I'll be bringing it again next week.
Overall it's quite a fun game! We might switch to Settlers of Catan if people grow tired of it.
