I'd be glad to show you around some of the courses around Seattle. One of my favorite aspects of disc golf is playing a course for the first time. If you let me know what you're most interested in doing-- such as how many courses you'd like to play, how far you want to travel, whether or not you'd like to play a monthly acepot/weekly doubles, etc.
Perhaps you could get on dgcoursereview.com
(not sure if that's the right url) and decide which courses you're most interested in playing.
--Didn't see Mystjava's post before submitting, but I agree with the courses suggested and would add these to that list: Lakewood DGC (West Seattle/White Center), White River(Auburn), Riverside (Sumner)
Also, Mountlake Terrace and Mineral Springs(North Park--my home course) in N. Seattle-- not premiere courses but close to Everett and only 20 min apart-
Up north of Everett there's also Arlington DGC, Lake Stevens (funky but fun homemade baskets), Sedro Wooley, and Mossy Roc (outside of Bellingham).
