Not bad on Blue on 5/19, we started around 12:30, in late afternoon, some mosquitos. On 5/20 in Siamese Ponds area, black flies were enough to annoy the 8-14 year olds. Couldn't stay still for long.
We were up on Westkill this weekend, the bugz weren't in full bloom but enough to make you uncomfortable. If it gets warmer I am sure they will be out in full force.
