[amsat-bb] How much Precision for QTH?

Hi all,

I was wondering how much precision is needed when indicating my QTH on a QSL card. Since my station is currently my mobile rig, mounted in my car, I sometimes operate from different locations. Mostly I operate from the driveway of my home, but I have also operated from my daughter's elementary school and my work parking lots. Both of these locations are within a 2 mile radius of my home.

I know if I were in a different grid square I would need to indicate that, but when operating within the same grid and even the same subgrid how precise do I need to be?
