Took my nephew and brother in law to Long lake. We saw hundreds of birds and had 30-40 committ to our decoys. We downed 17 and quit by 8:15. Almost a three man limit. We took 3 lesser scaup (1 per person limit and didn't want to risk taking more than our legal limit. The rest were ring necks and a couple of wigeon. Be careful when putting decoys in as the lake drops from 2 feet to 5 feet quickly. Use the boat at the opposite end of the lake to set your spread. 
 

We took a look at Salt Lick and saw at least 150 ducks on that lake in the SW corner. My nephew snuck up on them at 100 took off at one time. Beautiful.
