Having attended the GYC this year with Tyler, I can say that it was great. The speakers they had lined up and the seminars that were presented were fantastic. Each morning and evening, from 6:30AM to 9:00PM, were jam-packed. There were anywhere from 5000 to 6000 people that attended this event.
David Asscherick's messages were right on time and well delivered. We could tell when 3ABN cut their broadcast off, but then he would go on for another 20 minutes or so to finish the message and present an altar call.
If anyone gets a chance to go to this event, try and take advantage of it. Next year will be in Minneapolis, MN and the dates are Dec. 19-23. The only suggestion I would make if you want to go is to make your reservations early as to take advantage of the early bird registration.
