If you can, please leave a donation, however modest, at the smaller museums and attractions that accept them. Most of them are staffed by volunteers and receive little outside funding. They need this money to remain open. If you are traveling a great distance, call ahead to confirm the attraction you plan to visit is open.
Some places change hours or simply close in bad weather.
Also check the Pocono Record or any of the free publications and brochures available in front of area businesses. When taking pictures outside at Poconos atttractions, remember to place the sun off to the side or over the shoulder of your subject to avoid the squinty-eye look. Also, to avoid stiff poses, have your subjects do something rather than just stand still. Candid shots look more relaxed.
