Hi there, in addition to being a fellow portlandhikers.org contributor, I'm a co-instructor with NW Photography Workshops. These weekend workshops usually fill-up well in advance, but we just had a couple cancellations for the upcoming Crater Lake Workshop on Oct 3-6. If you're interested to learn more, check it out at:

btw, I don't usually promote things like this on portlandhikers, but I thought there might be some interest by folks in this forum, and time is short!...
Thanks & take care,
