We only saw one accident on our trip down. I don’t think it was a serious one. Going thru Ohio on I-75 was not much fun. About 75% of that portion of the trip was under construction/road work. The Cincinnati area was not nearly as crazy as the last few times, Traffic moves along pretty well there, despite being bumper to bumper. Travel thru the Louisville area wasn’t bad. It moved along pretty good. The approach to Nashville was backed way up. VERY SLOW! The same can be said about the approach to Memphis. I don’t remember having these issues on other trips. The rest of the trip moved along pretty good. Houston traffic was a bit crazy, but that’s Houston.
One further note: At this time, gasoline here in the Rio Grande Valley is $1.85 a gallon, or $0.65 a litre (with exchange rate).
