Approximately 60,000 people descended on Anaheim, California this April for the 2015 Star Wars Celebration, and I was one of those people. Day 1 of the event started off like many of these events – waiting in line to then wait in another line before finally getting in and working our way through the crowd.

Since the first day was on a Thursday, there weren’t that many people dressed up, but a few did take the time to come out in costume. Mostly, however, day one was spent checking out the booths and attending a couple seminars.
