Towns near Phoenix compared
2 of the 6 nearest places get more painting days, the most in Glendale (102 a year, 6 miles southwest); 1 gets fewer, down to 55 a year. A gap like that between towns is usually elevation, a coast or a lake, which is why a painter from a few towns over can be on a different schedule. Peoria is read from the same station as Phoenix, so its numbers match; the real difference is the distance from that station.
