Two more days until I depart. I hope I'll be able to sleep at night until then. ;D

I was wondering about something today though. I live at about 700ft above sea-level, and this area is about 6000ft above sea-level. What is that going to do to my trajectories? I would imagine that my bullet will strike a fair amount above my POA when scopes are zero'ed out here at 700ft. ???
