A majority of buses are equipped for ADA transportation. Guests with power scooters may have to wait for a properly equipped bus to arrive. The bus company is in contact with all their buses via business band radios and may be able to dispatch a lift equipped bus. Xenia HS remote parking is the preferred location for Guests with scooters.
Yes! We have close to a thousand ADA spaces, most of which are on grass. They can be accessed either through Gate 3 or Gate 4 off Fairground Rd. You must have a state issued placard or license plate. Please have these visible before entering Gate 3 or Gate 4 off Fairground Rd. No claims of ADA compliance will be honored without a state issued placard or license plate. Space is available on a first come first served basis.
Scooter rental is in the center of the two ADA lots near the main entrance to the show. The farthest ADA space is approximately 700′ from the scooter rental. Transportation is available for offsite parking to the Scooter rental tent
No firearms or weapons are permitted on the Greene County Fairgrounds complex property. There are NO EXCEPTIONS.
A Will-Call tent near the Flea Market, with a claim check system, will be available for people making purchases that are too large to take to their car. This Will-Call booth is located between Gate 1 and Gate 2, just inside the fence. A claim check can be acquired at the Flea Market office and guests can leave their purchases at the Will-Call booth. After getting their car, the claim check can then be used to enter Gate 2, to pick up their equipment, after which they will exit through Gate 1. Be sure to obtain the Flea Market Will-Call claim check from the Flea Market Office BEFORE leaving to pick up your vehicle. No access to the Flea Market area will be granted to any Will-Call claim check holders.
Please enter in Gate 4. Motorcycle parking is in the paved parking area just inside Gates 4. Vehicles parked outside marked areas will be towed.
The determination whether on-site, non-ADA parking will be available for guests will be made on Wednesday or Thursday by Greene County. Their decision will be carried out by Hamvention staff and security. Listen to Talk-In (146.94-) for the latest information. If heavy rain is forecasted, then non-ADA guests and ADA overflow will need to park at Remote Parking locations. See the locations on the Parking page. Committee and Media will continue to use their lots. Enforcement will be stepped up to ensure proper hanger passes are displayed. Long-term, we are exploring options to improve drainage and parking areas. ADA will likely remain on the grass.
Remote parking and taking the free shuttle bus is the best way to go even if the parking is not full. Please familiarize yourself with alternate parking locations before driving to the show as the on-site lots may become full before you arrive. Visit the Parking page for more information. Listen to Talk-In (146. 94-) for the latest information.
Large Vehicle Long term parking: Large vehicles will be accommodated on paved parking area in the rear of the parking field. Take Fairground Road to Purcell Avenue then right onto Alameda Drive. Enter Gate 5 and park where directed in the paved parking area. Tour Bus Drop-off (optional): Enter Gate 3 and follow bus route. Tour buses will be permitted to discharge passengers nearer the show. However, it is recommended to park your bus in the Large Vehicle Long term parking listed above and utilize the Golf Cart shuttles to navigate to the show. Parking first will help your passengers easily find you after the show. Campers, large vehicles and trucks parked in the transportation bus station will be towed.
Greene County Sheriff will NOT allow overnight camping in vehicles in the parking areas and the Flea Market. Deputies will be patrolling to enforce this regulation. Campgrounds are available on the Fairgrounds property through the Greene County Expo Center. Visit their website: https://greenecoexpocenter.com/events/hamvention
