A-fest Dallas was my first big con. It was great and a lot of fun. However, be warned that anytime you get a LARGE number of people in one event there will be idiots and morons that will ruin it for many. Hopefully the moronic behavior can be limited this year and won't ruin too much of the fun. Last year someone tripped a fire alarm during the rave and since I have severe asthma that is triggered by cigarette smoke I wasn't able to evacuate (since the first thing anyone does when they exit the building is light up)and had a staff member up in my face yelling at me for it. However, it was handled well by the hotel staff and that was the only staffer I had an issue with (she was rather rude to others as well but what can ya do? There's at least one in every group). The rest of the staff were either in their own little world or very nice to me.
All in all it was a great event and I hope to be able to make at least one day of it this year. Sadly, I can't make the whole event due to a family birthday.

But I'll be in Durant for that so I'll be close enough that we might go the rest of the way and play. ;D
