I am really glad you decided to go. Hopefully next time you won't think twice about going alone if you have no one to go with you.
Since my sister moved to WA I have gone to the Road to CA show alone, and the San Diego Quilt Show I usually do at least one day alone. (If the show is really good I like to go 2 days to see anything I may have overlooked the first time.) I have a few friends that like to go to the shows and I will go with them, but I do like to go alone too. (Really so I don't say something out loud that I could quickly regret, you never know who is standing next to you or behind the quilt.)
