The lower level seating is all assigned and NOT General admission. Season tickets are I think $4 for children and $8 for adults. Not sure if you can pick up any on stubhub or the official ticket office exchange (I know that have one for the other sports, so just assuming). All the meets are pretty well attended, the kentucky meet last night (not a premier opponent) had 9k out of 12 k capacity so GA seating can be annoying if you have anymore than 3 people trying to sit together and not getting there an hour+ before meet. Driving to the ODome is the most daunting aspect of it, since it is on campus you have to fight small campus roads with a multitude of cars trying to get close. You can park in the commuter lot and walk up to the Odome, about a 10-15 minute walk up hill. Getting into the actual venue is simple, they do have metal detectors and no food or drink can be brought in! So I would plan on getting on campus by 6 for a 6:45 meet. If the travel gods are with you, you can watch the team warm ups!
