The Gryphon statue is located on a very busy intersection, so you can't just pull over. You can park at the University and walk up -- but it can be hard to find parking and you have to pay. There's a hotel and restaurant kiddie corner where I parked and walked up, about 5 min. (You can indiscreetly park there for a short time).
To Claim the virual, have your picture taken with the statue
