Just a follow up to this Post.
We arrived back yesterday and had an absolute blast.
The campsites at Shaw provided for a great Base Camp. As we were able to ferry over our cars, we were able to factor in the luxury of car camping, coolers, etc
For the uninitiated, Shaw is a very undeveloped island in the San Juan's, the only commercial interest is a general store that appears to have not been modified since the 1930's.
We are able to get in a trip around Shaw one Day, At trip to Brown island another and plenty of playing and discovery.
I would recommend this trip and plan on going back.
