Games start at 10 AM and start every 2 hours with the last game at 8 PM. Tickets are sold at the door. In past seasons that has included a free voucher for a bad nosebleed seat at a TWolves game. Don't know if they'll do that this year or not.
I agree with Ole, Memorial vs Sibley is clearly the showcase game. Bruesewitz and Maymon are both do it all players for their teams. Memorial will be able to throw a ton of guards at Sibley and will really pressure them (even more than Hopkins). Watch freshman Junior Lomomba in that game too for Memorial in addition to Vander Blue and Maymon. Eden Prairie is on fire right now, their game with Rodney and Cooper should be very interesting. While Badger did qualify for the WI state tourney last year, they're not in the coaches poll (top 15) so don't expect much from the Hopkins game. The Tech vs Roncalli game may or may not be interesting, but the Roncalli motion offense is worth it.
