Do come. People are friendly. I am personally but only after about 11 a.m. It is semi-rural..was old dairy farms around and now almost urban sprawlish. Hard to find..for me, yes. For others not geographically impaired, probably not..but I get tangled up in Bellevue traffic each time.

Perhaps you could meet someone say in the U. District and carpool with them. I would recommend getting to Seattle late morning if you could and traveling light. Buses are very good in Seattle and fine from the airport to downtown, and then a straight shot to almost anywhere, including Carnation itself. It is the Camp Don Bosco camp. Perhaps someone can show you a map to it. Especially if you drive you want to get there early (daylight) and avoid the bad traffic that occurs.

Oh, you can go on Mapquest and it might show it.
