Anyone travel north or south on I -75 and east west on I-10 needs to check travel advisories as they closing these roads among others due to major brush fires in s. Ga and ne Fl It took us 3 hours to go from exit 437 to exit 434 ( us 90 Lake city yesterday.
They were closing again today. no suggestion except go to Fla. Highwya patrol and other florida road conditions sites on google,/yahoo, or Dogpile. there are a number of sites to get information. the folling is a good to get info on .
