i have done this and if they aren't the same times you go out with the latest and come in for the earliest,i usually lose an hour,i have won money from both tourneys at once and never heard any complaints.i have no problem with it as long as rules are followed.i have even seen 2 small tournaments merge on the ramp and combine money??can't make everyone happy but i feel i can win any one i enter as well as the next guy..
