 Go fishing. Help salmon and make money. You can do it through September 30th by catching northern pike minnow and turning them in for cash. Here's how it works. First, register at a designated station on the Columbia or Snake River. Then, go fishing. At the end of the day, turn in any pike minnow you catch 9 inches or longer and look for the ones with tags worth $500. You'll get vouchers for those pike minnow you turn in, and you mail those in for cash. Find out more at pikeminnow.org.
