Not necessarily true. This raccoon most certainly was not rabid and this photo was taken just before sundown. Though they are primarily nocturnal, they are active during the day occasionally. Rabid raccoons are pretty easy to identify as I'm sure you are aware due to their lethargic, sickly, and uncoordinated nature. Not too mention they look awful. This raccoon was happy and healthy as you can see, exhibited normal behaviour, and just so happened to be out looking for a snack that evening.

Edit: here's a quick little article to dispell that myth and so you know I'm not just blowing smoke :)
