I think you've got it right. BroganMc would know for sure, when she logs on. She's got the exact mileage down for every location at SSR.
One thing to remember about the SSR maps is that "things are closer than they appear" I hear that over and over again while on property. If you like to walk, everything is a pleasant walk unless of course it's mid-day and 98 degrees and outrageously humid.
