Though the Robot Competition looks to be fierce. I think the biggest win will be finding a Parking Place within 1/2 mile. With all the construction, show up early and bring your walking shoes.
Next be prepared for Saturday evening when there is a Concert in the Toyota Center. (Not going to advertise who) So knowing the parking lots, most will charge you $10 for the day, but at a set time the price will go UP and they'll probably make you pay for the Evening price also.
Then we're in for the best part, with a major event downtown, the TRAFFIC.

With all the road construction it's going to be a major mess.
Good Luck to all the Teams at the Competition, and Good Luck to all the Mentors and parents driving to the event.
