Trust me brother,, mission beach is PLAYED OUT! I went there last week with a hunting buddy and I literally started cracking up with laughter.. 5 MD'ers (7 total) nearly ran into ea other and no one wanted to pull away from their grid lines. I said "lets get the %^$# out of here." What a joke! Mind you, they were 75 yr olds with 1985 metal detectors but still.
I work Graveyards 8-6am. I'm about 2 miles from any decent beach and go for about 2-3 hrs ea morning until I get tired and or people start flocking and getting in the way. Right now every beach around here is the same.. Fresh dry sand drops and 99% of that is coinage. Lucky to get a few bucks on a 4 hr hunt. Water conditions as you know in Santa Barbara are prob the same here. Knock you down waves until you're eyeball deep, then its swells to a ft over your head. Anything shallow is pointless due to no erosion.
I often head to OC just to get a change of pace. With the same results usually. I'm looking to get my Scuba cert then I'll be out past and or under the waves.
