There is no free parking. You may get ticketed and/or towed.

1) The closest place to Wilson Hall where you can park is the Terrace Place garage at 2010 Terrace Place.  It is just a block away.  Visitor parking is limited to spaces numbered 41–92.  You note the number and go to a pay machine and pay for that number — no need to return to the car.  It costs $3 per hour, and $15 for all day.

2) Previously I posted info on a tag, but I later learned they don’t sell them to anyone not affiliated with VU.
