Down around Norman it's like that everytime we go through there. Bumper to bumper, then all of a sudden it opens up and every is back up to 90. WTF?Does anybody remember the last date when you could drive I-35 between Edmond and Davis without coming to a complete stop - regardless of time of day? Additionally, there are at least 2 permanent "areas of slowing down to 40 for no reason" on the same stretch of highway.
