Can't figure out why some days my commute to work is through heavy traffic and some days, like this (Friday) morning, it's all smooth sailing. I enter the Hefner Parkway off 122nd and drive south to the I-44 exit and head east. Generally very heavy with numerous stops and starts. Sometimes it's just heavy volume and then of course the occasional breakdown or wreck. But generally there's no rhyme or reason why some days it's heavy and some days it's light. Anyone else experience this on your commute?
