I hear you GW and it sounds like you will have an iPad if you need it. I was on one of those local VFR navigate by sight flights earlier this spring and I stayed out just a little too late. The temp/dew point spread was close all day but as I headed home the fog just started to form and as I approached my home airport I suddenly couldn't recognize anything on the ground. I used my GPS and got right on top of my home field and then I could see it looking straight down, landed OK. Sure was glad for a little technology that time.
