After seeing my kids dig four times as many sandshrimp each day as they need to use to fish for flounder at a beach cabin out by Marysville... I started wondering whether they could subsidize their Pokemon card buying habits by selling some to fishermen (or stores?) in the area. Is anybody interested? Since I don't buy them from stores or use them for salmon fishing, what's the difference between "good" sandshrimp and not so good ones when you buy them? Any suggestions?
