I'm a helper on mostly residential route and been doing it for about a month. I don't get lost in the DIAD anymore with simple LAs like leaving a sig required package at neighbor's house, but I don't know how to do multiple Left-ats so they count as one stop or multiple stops according to whats appropriate.
Your original question has been totally threadjacked. But, don't worry about how to do any of it. You only have five more days.
