Took my son to the car show. We live in the suburbs but grew up and went to college in the city so I'm very familiar and comfortable with the city but the parking is terrible and they gouge you, $28. The convention center is large and they was no signage for where the entrance is. All the doors we tried were locked and had to walk along the outside of the building until we found a door that was unlocked, by that time we had encountered others who were in the same situation. They could have put up a few disposable plastic signs that stated "Entrance --->"
