What is Thunder? Why is it so Loud?

Thunderstorms can be scary.
Lightning is loud and dangerous.  Perhaps if we understand what it is, it may rattle our nerves a bit less. I found this article to be a great explainer, complete with animation:
Thunder is the sound that accompanies lightning during a thunderstorm. Sounds simple enough, but why does lightning even make a sound?
Any sound you hear is made up of vibrations. The vibrations travel as a sound wave through the air, until they reach your ear. Lightning is a huge discharge of electricity, and this electricity shoots through the air, causing vibrations to be formed in two ways:
1. The electricity passes through the air and causes air particles to vibrate. The vibrations are heard as sound.
2. The lightning is also very hot and heats up the air around it. Hot air expands, and in this case the air expands very quickly, pushing apart the air particles with force and creating more vibrations.

Washington Fish & Wildlife stock ponds with rainbow trout

ASOTIN, WA - Good news for local fishermen who aren't getting their fill along the river, the Washington Department of Fish and Wildlife is preparing to re-stock local ponds. 

WDFW leaders said as soon as this month through June, three ponds in Asotin are getting fishery raised rainbow trout. Those fish grow to be roughly half-a-pound to a pound in size. Between Headgate pond, West Evans Pond and Golf Course Pond, the agency is stocking 35,000 rainbow trout.

Fishing at Headgate Pond is restricted to only April 26th, but anyone can get fish all year round at the other two local ponds.

"A lot of our streams and rivers are very restrictive in the fishing because we're protecting anadromous runs," said Madonna Luers. "So a lot of these lakes and ponds and smaller waters need to meet the fishing demand."

Luers reminds fishermen that if you haven't gotten a new permit yet, the 2013 permit expired last Saturday on the first. You must have a renewed license to start fishing for the 2014-15 season
