When I was growing up in Jersey City in the 1970s, my family went to a harvest festival on Staten Island each year, complete with hay rides and pumpkin carvings. If you take your family to an event of that sort, bring a camera. The sun will work against you, so try to put it behind you when you shoot. If you get a wide range of exposures, from bright light to deep shadow, you can tweak the photos afterward on your PC. Even if a photo looks hopelessly underexposed, you can use the tips in "Improve Your Exposure in Tricky Lighting" to enhance the scene dramatically.
