you're going beforehand--many of us have been steered wrong (pun intended) by our GPS systems.
When I went for the interview for my previous job, I was told the company was spread out over three buildings; two shared a parking lot and one (the one I eventually spent most of my time in) was about a quarter mile down the road and could be reached both by main road and access road between it and the two other buildings. Even with detailed instructions on how to get to Building #1 where the interview would be taking place, I still wound up accidentally going to Building #3 first. Luckily, I figured out where I went wrong pretty quickly...and I'd left with plenty of time for wrong turns, slow traffic, accidents, etc.
