I didn't get a t-shirt either. I got in line for the ERT, but tried the test seat and the guy said I wouldn't fit. So I walked over to the exit and sat. There I met gabelogan who also couldn't fit, sorry bud.
Later, when I met up with gigacoaster, violakat, PhantomTheater, pkiruler, and keiko_coaster, they forced me on. Kat reassured me the test seat was inaccurate. So I gave it a shot and fit with the help of Mr. Cory Butcher. Unfortunately, they had ran out of shirts by then.
