UPDATE: This ain't Mazatlan. -_- It's a picture of "Lover's Beach" in Cabo San Lucas. This is proof that your brains really turn to mush on vacation, and that it's really, really important to fact check things before you upload them for the world to see.
Taken from a cruise ship leaving what I thought was Mazatlan, Mexico (it was actually Cabo San Lucas). It really was a strange looking sky- it actually did look that pink in real life.
The preview image used Nemed's great, and most importantly, free "Led Cinema Display .psd" icon, which can be found here: [link]
