Naw really, i haven't really seen anything out of the ordinary at our local lakes, but, maybe 12 or so years ago i was surf fishing close to Ensenada and on my first cast i hooked a fresh Maxi Pad w/a super fresh red streak down the center! I should have known with that sickening stench in the air...their raw sewage dumps straight into the ocean!!! Needless to say i didn't keep anything that i caught.
