hey guys, surf newb here and got the surf fever already. Hauled in a couple black tips and some whiting so far but bait is getting expensive when the crabs want a feast. Keep seeing everyone talking about catching sand fleas and just wondering if anyone could point me in the direction or post a how to or guide on catching them. Bought a "sand flea" rake the guy at the bait shop said was a must but not really to sure what I'm looking for or how to go about it. Thanks in advance.
