Mention the federal Department of Transportation, and Gainesville Mayor Danny Dunagan sees red and gets hot under the collar. That pretty much describes Dunagan’s angst when he found out this week that federal DOT wants the recently dedicated Deshaun Watson Way street sign leading to Gainesville High taken down because the sign’s colors are non-compliant. Watson, a Gainesville High star quarterback who led the Red Elephants to their only state championship, guided Clemson to the national college football title over Alabama in January.
