I like driving just about everywhere I take loads to, including Canada. Yes, the North central areas are somewhat boring and some of those states seem to have way too many bored cops looking for trouble.
I have found that the more times I go on a given route the shorter it seems. No, it hasn't physically gotten shorter but each time the trip just feels like it goes by quicker and that can take the sting out of the runs that aren't so enjoyable.
The states with faster speed limits are great, but I like that because I like to haul ass. But I have learned to use the cruise and keep my law bending to 3 mph or so over the limit and so far that has proven out as OK. But I always go the posted speed or a little less in construction zones and when passing through the cities and towns.
Almost every state has scenery of some kind that is easy on the eyes, and you can find sociable and anti-social people most places too. But some states have pretty crappy roads, Massachusetts, Oklahoma, Texas, Illinois, Pennsylvania and Minnesota come to mind.
There is only 5 of the lower 48 states I haven't been to yet, Michigan, Rhode Island, Vermont, Florida and Louisiana. I suppose that my perspective might change if and when I visit them, time will tell.
I just love to drive.
So you need to add a choice to the poll for "I am a glutton for punishment and like it everywhere".
