Dress code is casual. Wear your HIFICO shirt, 2a related shirts, shooting jersey, hunting vest, whatever to represent. In good taste of course as this is a peaceful rally and we're building relations with the legislators.

Parking suggestions
Most of the parking around the capitol area will fill up quickly so get there early. Remember to feed the parking meters or it's a $25 ticket. There are other surface metetered stalls in the area like Iolani Palace and on the street, but it's limited to 30 minutes to an hour. I recommend taking the bus, biki bike, and alternative forms of transportation.
State Capitol Underground Garage - Enter the driveway from Punchbowl St across from Queens Hospital. Opens at 6:30am. Quarters only. There is a change machine in the center of the parking lot.
Dept of Health - Surface lot with entrance on Punchbowl Street. Pay with a credit card at the machine.
