I’ve seen sharks underwater, but this was in the tropics with 60′+ visibility. There’s something really scary about seeing it emerge from the gloom. No matter how wonderfully intellectual & informed we are. :)
[...] more white sharks were sighted on Sunday right here on La Jolla Shores in San Diego, combining with last week’s San Onofre sighting to give San Diego County a little “Summer of the Sharks” feeling. According to the 10 [...]
