You would be able to join the group in progress when you arrive, like at Alki Lighthouse, then pick up what you missed on Thursday the 9th.. That is the beauty of how Derith has this planned out.

I would suggest that you should still email Derith and CC me, of your possible interest and that way we can see if it might work out for you..

Derith knows this area like the back of her hand and the words "Private tour" mean just that..
