Over the last 20 years the busiest season has moved to September and October.  Sure Summer is still busy, but Fall is now the Upstate, NY and the Northeast USA go to season. The cooler weather, Fall foliage or generally hotter summers has changed the way people plan. The Hudson Valley is the greatest place It is known for beautiful Falls and great refreshing days.  I still love the summer weddings and just did 4 in a row with heat indexes of over 100 degrees and the photographs look great.
