Okay...let's narrow this down...
Springfield has a beach, since many scenes take place at the beach or the waterfront. This excludes all but the coastal states.
It can't be in the south since they have enough snow to need a snow plow service (Mr. Plow). This also excludes Southern California.
There are huge mountains around and they can be easily seen from the Simpsons house in the episode where Homer climbs the mountain.
So where is there a coastal state with a beach, mountains, and snow in the winter?
Thats where it is.
