You're in Bellevue, eh? DBS and ForestFire are definitely the closest to you. ForestFire may/may not be open - you'll have to check here on PBNation to find out - just post a general question in the Washington forum area and someone will respond. DBS has indoor field in Everett, outdoor in Snohomish. ForestFire is in Lake Stevens.
Have not ventured north of Everett to play, so I can't offer any suggestions if you want to go further north. South of you are several fields, although you'll be going to Puyallup, Graham, Buckley, or Tacoma (JBLM). Those are all within 70 miles or an hour and a half (give or take) from Bellevue.
