Nothing beats seeing nature wake up, problem is you have to get up pretty early to capture it. - Get up, get dressed, get the gear together, drive to your destination, get the gear out, hike to a spot and wait. That means 4:30 am this time of year.
Will it be cloudy? Foggy? That's part of the fun, and you never know what you're going to see. Most of the time I set up and discover something else I'd rather capture - like this: the Illinois and Michigan Canal just before sunrise. You often find the best colors just before sunrise or right after sunset.
