wide loads rate cops here in NYC area... and to get into manhattan, they have to be scheduled. but last year, in a bit of morbid comic relief, i got stuck in a traffic jam just out side the toll booths for the George Washington bridge (a major portal from NJ) the traffic jam was caused by a convoy of wide load trucks (carrying massive cranes and earth moving equipement) that because of the emergency was going thro during daytime hours --only it wasn't -- the load was too wide for the toll booths, and they had move "zipper" barriers to open up the spaces...

do your artic travel down the road in convoys? tailgating each other, riding in each others slip stream? 10 or 20 in a row? I saw a convoy this summer in canada.
