When we went crabbing as kids we didn't have the Facebook and the Instagrams and the texting and the GoPros. We had hotdog and string.

Here's a great tip for capturing fog-free underwater video with your GoPro:

Moisture buildup is a huge barrier to crystal clear underwater footage, and the anti-moisture strips GoPro sells aren't exactly a bargain. Instead, wrap a few grains of smashed rice inside a very small strip of tin foil, narrow enough fit between the camera and casing. Be careful not to let any rice escape! Three strips is usually safe for a day of underwater shooting, and best of all, costs less than a hotdog and string.

Now please excuse me, I have a quarter-century of crabbing to make up.
