I went back to the same school after work again tonight, and I'll be danged if I didn't find another Walking Liberty Half! Once again this one was about 6-7 deep and produced a solid signal on my E-trac. Obviously this school hasn't been hunted very thoroughly. I got another Merc too. Not as many wheats this time but I'm not complaining about that.
I suspect that I'll be heading back to this school again this weekend when I have more daylight. thumbsup01
