We had a campground picked out north of Tulsa, which would have put us at about +/-370 miles, but when we got there it was 2:30 and we decided to go through Tulsa to beat the morning rush hour. We hit the evening rush hour in construction, Yea. We then could not find a campground until halfway to Oklahoma City. About 450 miles total.
We started out in rain in the morning and it got worse as we went along. A couple of very heavy downpours. Kept looking for those Oklahoma funnel clouds.
