i have allergies to perfume,(most are wearing some, so you really cannot hide from it) so by end of day one i have a massive headache that last for at least 5 or so days(even with antihistamines and nose sprays), also my wrist is sore so i cannot write notes (also hard to with a headache). However now by the time our conv comes in mid July, I will be able to get more out of the convention instead of just being there in body, and my mind will be able to retain a lot of the info. So these videos are a huge help, so Thank You Very Much ??
