So I found a great area between Auburn/Kent with a HUGE flat field that worked out great - I just bought my first complete flying plane (Horizon Sport Cub S) and flew it there today for about 30 min - LOTS of space. Some blackberry vines in areas, but there's a great incomplete road that bisects the fields so you've got a great runway, too. I just need to make sure the local homeowners have no issue, now.
