The circles are crops, anywhere from wheat to corn. The irrigation sprinklers are on a long pole that rotates around an axis. That is why the crops are circular.

They sound like Water Reclamation filters. In low-water areas, sewage water is recycled into drinking water. One of the steps is to "purify" the water by running it though live biological filters such as plants. THAT may be what you saw in the circles. Some plants can live on the "crap" in the water, breaking it down into more water, and other non-toxic materials. Note that these are NOT crops, like corn or wheat. THOSE fields are SQUARE.

Don't listen to Gary, he is a retard. The other person is right. It's from irrigation. PS Shut up Gary

Is there a flight from Frankfurt Germany to Phoenix Arizona

Is there a flight from Frankfurt Germany to Phoenix Arizona?
I'm wondering if there is a flight NON-STOP from Frankfurt Germany to Phoenix Arizona. It will be my first time flying internationally and so I want to go non-stop not with stops. I'm flying alone. And if your 15 do you have to be accompanied to an adult since I'm still a minor?

Well, you could look on any travel site such as www.Expedia.com. But no, there are no non-stop flights for this route. And yes you can travel by yourself at 15 years old. But you will have to see what the requirements are for the airline you choose.

Does it cost more money to book a flight 6 months ahead

Does it cost more money to book a flight 6 months ahead?
I was booking a flight to Phoenix, AZ in June, it said that it cost $365 for a round trip ticket. I checked if I had wanted to book it in Feb. and it only cost around $170, for round trip. And I was booking both on Tuesdays, which are supposed to be cheaper. Any advice? Please help!!!!

Usually you get a lower price if you book ahead. But here, it seems you are comparing a February flight to a June flight, which may differ because of high/low season. Meaning, there is probably a lot more travelers in June (summer, vacation), so the airlines will charge more during that high season.

I would sign up to get email blasts from the airline, they will in turn advise you of seat sales, there isn't a right time to book really , to get the best value follow the seat sales. Check the airlines website for details.

I normally get plane tickets 4-6 months in advance. Never get tickets on the weekends, or Monday or Friday. Really the best days to get them are Wednesdays and Thursdays. With rising fuel costs and airlines raising their tickets every few months, its better to get them well ahead of time. Keep checking online for the flight you want. You'll see the price change up to 4 times a day.
