The convention schedule lists the following trade sessions:

Wednesday 9am-4pm
Thursday 8pm-?
Friday 6pm-?
Saturday 7pm-?

Are these absolutely the only trading times? Or, will the trading room be open daily before the show opens?

(P.S. - See me at the convention for a "Slab-Free" or "Slabbing Sucks" sticker to wear on your lapel)
