Sign of the Times

Been spotting lots of signs around town, some are posted, some are just indications of the end of winter or the start of spring. 
The persistent trouble maker who alters signs around Cornell must have been satisfied with the presence of winter this year, I didn't see any with the words " trail maintenance" covered up.  I think Cornell puts up the sign in the bottom picture just to let people enjoy the first spots where the ground reemerges.
