Hospital? Heliport? Hippodrome? Haunted house?
Those all sound interesting, but no.
The big H simply represents the human surname, Heal. Around the world, human Heals are a rare breed, and this site pertains to just one tiny subset of human Heals domeciled in the northern part of the state of Virginia. To be more accurate, it pertains mostly to just one member of that subset, the human Heal known as Jon.
Occasionaly, Jon may upload information pertaining to other members of his familial Heal subset, but for the most part, what appears on this site are projects and ravings for which only Jon can be blamed.
