Yes...a group trip would be great.
Steven...I dont know how far Duck is from Bellingham, but my guess would be pretty far.
Float tubes are almost impossable to use on Duck as the max depth is 6 feet and weeds grow to the surface.The best way to fish it would be in a canoe or a rowboat and some people use driftboats.Fly fishing is really good with surface poppers.Have any of you been to this lake?Anyway...if you want to do a group trip...email me.
