If only tahoe snow fell in chicago, that would be so nice... =P
An easy solution would be to overnight all the pizza's in the freezer... but I assert that there will still be regional taste differences.
I've visited the bay area quite a bit, when my folks lived out there; lou malnati's deep dish is still the best by far.
I do notice that the food selection in the bay area is a lot leaner and healthier, hence that was my point in the bias. The midwestern diet is much heavier, with a bit due to seasonal patterns. Need some of that extra padding to stay warm.. the high for tomorrow is 31F in chicago, while the low right now in Mountain View is 51F....
