Two other suggestions: 1) if you can use any help from the TravelBuzz moderators as to the best local/regional forum to use, just PM or email us.

2) If you're driving through an area supported by reliably updated maps of local traffic conditions, check them out before you start. My business trips often require 60-75 mile drives to/from airports through oft-congested So. Calif traffic and checking, e.g., the L.A. Basin Sigalert map has saved me lots of time.
