I was in Iceland in August. It depends on what you plan to do. I did a horseback riding tour up north. I did wear mid calf boots. Take a rain/wind breaker, winds up north can be quite terrific as *Just Fred* reports. While there may or may not be snow. A few weeks after I was there, there was a terrific snow storm in the north.

I love Iceland. I have a multi-media slide show I will be presenting to a travel club on Long Island. It is a combo of 3 separate trips to Iceland with authentic Icelandic music.

Having grown up in Lancaster County, PA, and calling it home until I finished college, was married, and we went to Belize for three years, I appreciate you wanting to find lovely photo opportunities there. I will emphasize what Gaddysmom has said about taking pictures of Amish. Please do not try to sneak a photo after they have refused your request. My suggestions is to drive around the area south of New Holland (including Intercourse, Gap, Paradise, Gordonville, and Smoketoown) and north of US 30.

Then when you see some Amish folk working outside near the road, stop, and talk with them. While they do speak Pennsylvania German, they are very fluent in English. After getting to know them, then ask about pictures. They would most likely be honored to have you photograph their barns, shops run by compressed air and diesel or gasoline engines, their white-washed tree trunks, flowers and fences, and even their cows, horses and cow-milking. Just be respectful and do not get in the way when they are working. From grade school through college, my family lived next-door to Amish families and their farms. You will learn much from the conversation. and it will make your photos that much more worthwhile even if you have few people in them.

One last item, there are two groups of Anabaptist Christians who derive buggies in Lancaster County. The official name for these groups, at least applied by scholars, are the Old Order Amish and the Old Order Mennonites. Their buggies are actually easy to tell apart, so don't mistake them. The Old Order Mennonites drive all-black buggies with almost flat tops. The Amish in Lancaster County drive buggies with medium gray sides and almost black tops with the edges of the top making a gentle roll at the edges to the sides.

Here is an excellent link discussing the ethics of photography and the Amish.

BTW, I am a Mennonite Christian and am not an Amish or Old Order Mennonite person. We drive colored cars and dress like most of the people around us,. But like these two groups, we take Jesus' teaching for agape love and peace and against violence and war very seriously. Like all Christians we value belonging to God's kingdom and practice baptism as a sign of committing ourselves to God and God's kingdom. --Richard (who just came back from a long weekend in Lancaster County to our home now in Harrisonburg, VA, USA)
