yeah, don't pitch the yeast til you get to your parents.
and you won't be able to move it from your parents until its bottled or kegged, as the drive back to the city will put too much oxygen into the finished beer.
i toasted a mostly full keg by driving it on a dirt road after hours on the interstate. kept cold, but the keg leaked so it wasn't sealed with CO2 well enough and tasted like old damp brown paper bags when I got home.
