As a veteran of a few Midwest Locost Gatherings I can offer some insights/suggestions. Those gatherings were 3 day affairs with a good deal of planning well in advance. The planner(s) would scout an area, usually close to something they were familiar with, but not always, but scouted way ahead of time, laying out blat routes, restaurants along the way, and lodging including camp sites.
I'm not from the PNW and still finding out about all what it has to offer. If someone more familiar with the area has any ideas i would be open to help in any way I can.
I'm not all that great at organizing either but there are a couple of experienced folks that I can confer with.
I'm all for this.
