I did make it to merchants millpond for a day of relaxed paddling with the wife- rented one of their old town discovery canoes- I was impressed by the "new" visitors center and the upgraded canoes and lifejackets since i was there 6 or 7 years ago.

also paddled (near Suffolk) through blackwater swamp/river from Zuni to County road 603. I used a short ww yak (wavesport Y) to help negotiate the swamp sections- plenty of deadfall and current to keep the first 1/2 of trip interesting. Had a wild feel to it. definately worth doing- just follow the current. If your uncomfortable paddling around and over trees in current then this trip is not for you.
Next time I visit my niece we'll try Bennetts Creek.
