If they ever have an NRA Convention in Pittsburgh again, here is a little tip to solve your parking woes.
There is a Goodyear Tire Fort Duquesne Blvd. store RIGHT next to the convention center. Instead of wandering around looking for a space a 2 mile walk away, bring your car with worn tires to Pennsylvania. Drive to Goodyear and have them replace the front two tires with brand news ones on Friday morning, and the rear two on Saturday. Pick up your car in the evening and drive back to your hotel.
