So I'm going to the beach this weekend (Wildwood NJ for anyone in the States) and wanted to take the new D50. While it's relatively common sense to keep the camera out of extreme heat and sand ... does anyone have any advice or experience with taking a camera into a possibly unsafe area? I figured I'd lock the camera in the car (in shade with windows cracked) when I'm not actually taking pics... and when it's on me I'll keep it in a backpack that doesn't look like a camera bag. Any other advice or experiences? I guess I always feel I should try to bring the camera everywhere I go since... that's kind of the point of owning a camera... but there are some places I should definitely disguise it where others I don't.
