With the closure of national parks this week, I'm sure there are photographers out there looking for alternate locations to shoot. My suggestion is South Dakota's Black Hills and especially Custer State Park.
With 71,000 acres of unbelievable mountain scenery, granite spires, grassy plains and lots of wildlife, Custer State Park could easily be a national park, but it is not and it is open as normal. It is also one of the best places in the country to photograph bison, antelope and deer with good possibilities of spotting elk, bighorn sheep and mountain goats.
Add to that the spectacular Spearfish Canyon in the northern Black Hills that is ablaze with autumn color right now and you have a compact location for the kind of scenery that makes photographers drool.
