The 37th meridian west from Washington is an archaic meridian based on the Washington meridian. It is currently located at approximately 114 degrees, 3 minutes west of the Greenwich meridian.[1] The meridian is used as a boundary for two states.
I've always wanted to see something like this in DiamondFire for ages, and would be great if added! But as Frosty said, other than custom weapons, there aren't many other uses of this, and I doubt many players would need to or want to utilize this sort of feature.
