I'm totally sure he was a nice guy and had good info to share and it's great that you hooked up with him albeit briefly, I'm just sayin' the more people you talk to, the better overall picture you'll get about the whole place and individual spots (good and bad). Whenever we're picking a spot that's near other people, I always ask whoever is around if it's cool that we dig there as we really don't want to hijack someone's active spot or at least make a point of saying hello, even from a distance. Odds are, and this has happened MANY times, those around us will come over to us at some point and ask if we're finding anything (not so much because they're so concerned that we're finding anything, but because they want to make sure THEY'RE digging in the right spot too any you're not doing better, heh heh). We take those opportunities to strike up some shop talk and ALWAYS introduce ourselves. Sometimes it's newbies, sometimes it's seasoned veterans. Usually everyone gets around to sayin' where they've had luck, and where they haven't. And if it's close by, they might even say that spot right there (and point) I had some decent luck. So next time you dig there, or right next to it. I'd say just be careful walking up to someone's sluice box uninvited, I get a little up tight when someone's checking out my riffles without asking me first, heh heh. I'm sure others would be the same way.
I'll post a pic of today's flakes shortly. Got one nice one that I saw in the dirt behind a rock that I dropped out of the bank. Didn't even make it to the sluice box. Wish it was a little thicker so it actually weighed something, but I'll take it, heh heh.
We're up there usually twice a week. Let me know when you're headed back up there and I'll see if I can give you some suggestions on where to dig. Nothing guaranteed and nothing massive of course, but I can tell you where we had luck before at least finding the flakes that you've seen me post ... without having to hike 6 miles one way.
And ... I'd support your GF's decision not to camp out up river. I'm not exactly sure it's safe, lots of bad **** has gone down up there. If you and a trusted regular want to go for it, perhaps, but just be aware of the warnings that many will tell you about and the precautions you should take. ~CT
