OOPS, I mentioned above the "Month Long" Quartzsite event... that is the annual gem show there:

Hard to imagine a million(!) people in that tiny community, but I have seen the aerial photos that seem to substantiate that.
Quartzfest is the "week long" Quartzsite ham radio event... Duh...

It looks like the 2014 times for these events were coincident, but my only excuse for mixing them up is that I've been nasty sick for last 5 days (flu??) and my head was clogged up tight and not working well. Seems to happen more and more, lately (Head not working, not the flu)
.
OK... squared away now. I'll keep checking the above Quartzfest website for when the 2015 dates are posted.
Thank you all again for the nice welcome.
