Welcome to the board! Good luck on your trip.....we love going in March for the NCAA games.....have a great time!!
I will be out there at the same time, have been every year for the past 15. Depending on where in Canada, make sure you get some SPF 10000 sunscreen... My white New England skin got burned cherry red at my first Sprint Cup race in the brutal March Sun! Nice, though. They were having a blizzard back East! Enjoy your trip, don't pack anything warm!
