Are there opportunities in today's economy?

Absolutely, some very successful business started in the worst economic environments. Now is a great time to seize opportunities for goods and services consumers and businesses demand. I knew a gentleman who owned a chain of liquor stores who once said " when times are good,people drink to celebrate, when times are bad they drink to forget, either way times are always good in the liquor business". What do you think are some other recession proof industries?
