Driving through Hamilton over the weekend, we caught a fleeting glimpse of something green when passing the McDonald's on Route 12B.  Could it be?  Are the Shamrock Shakes back for 2013?

I took a quick tour of the McDonald's in the immediate area on Sunday but didn't see any indications of the elusive shake that's as certain a harbinger of spring as the rodent on Groundhog Day.

Out for lunch today (Wednesday February 2nd) I spotted the sign above at the McDonald's in North Utica on Genesee Street.  It looks like the shakes are back in Central New York in all their green glory.

The internet's authoritative source for Shamrock Shake locating is ShamrockShake.com.

According to the site and observations from around the area, Shamrock Shakes can be found in the following cities in Upstate New York:
