I'm in Elmira, on the NY/PA border.
I haven't fed the bees, and there are plenty of stores.
Every day that it has rained, bees have been out foraging.
The only feed I have out is on nucs with new swarms in them, to stimulate comb formation.
Feeding when they don't need it is a good way to lose bees to swarms, as kathyp noted.
And if anyone knows anything about keeping bees in the rain, it's a beek in the Pacific NW on the west side of the Cascades.
When I lived there (Rainier, OR) one day my daughter asked me why the sky had turned blue instead of gray....
