Terry, the zone designation isn't for the average, but for the lowest 
expected temp. For instance, we get winter temps down to minus 10 F., so 
that's zone 6. On an average of every 10 years, our temp drops below minus 
20, so that's zone 4.  We have so many winters where our low temps are 
between minus 10 and minus 20, that I prefer to regard this as zone 5 on a 
good day. If you're shelling out money for expensive trees or shrubs, 
figure zone 4. But our average temperature is 22.4 degrees F above zero.
