Why is the summer hurting my businesses?

Most businesses in Arizona have a really difficult time surviving in the summer heat.

Why?

Well, for starters I think the economy being the way it is hurts most businesses, gas prices have increased as well as food. Now it being 100+ degrees out side doesn't help either. More people now a day are watching their spending habits and just don’t leave their homes, because of the economy and the heat.

What are your thoughts?
