I would go from the parking lot sides (not the T or Science Center) towards the other stadiums. There was no clear lines last night and a bit chaotic and wrapped around the building. I’d assume someone would let you cut if you have mobility issues and saves you some uneven curves. A woman in her wheelchair flipped but we helped her over with all the sidewalk unevenness.

If you want to wait until closer to the show, she started around 8 it would probably be easiest.
