Gull Whites
 

Have always done well in the morning for Whites but it always seem to slow around lunch. I've never fished an evening but do the whites pick up again?

Cant speak specifically for Gull but it does pick up in other lakes 2 hours before sundown and right until dark. Found this to be true on both Sylvan and Pigeon.

P.S. With the clocks moving ahead this weekend, one can put in a decent attempt until end of season to pick up some whites.
