The hobby of visiting filming locations can be a very fun experience but there are certain rules that should be followed to make a trip fun and safe.
1. Remember that you can take a picture of a filming location anytime from a public road. If you are visiting a house or private residence you should never go onto the property of a homeowner because that is against the law. Don't knock on the door and ask the residents questions or look into their windows as most filming locations use only the exterior of the house anyway.
2. When you visit a location that is in a public building such as a hotel lobby, grocery store, clothing store, mall etc. it is always best to talk to the owners or security of the establishment first before you start taking pictures. You show them courtesy and they will usually be more than happy to allow you to take pictures and even sometimes give you a tour of the establishment.
3. Some of the locations are in areas of a city that can be dangerous and because of that it is always best to not travel alone. Also, you could be visiting an isolated area and if you have car trouble you could be stuck without a resource to get help.
4. Be sure you make a mapping itinerary so you can see as many locations as possible so you can have a fun and safe experience. The last thing you want to do is not have the exact address. Also, I have done my best to give the correct address but there could have been a mistake in typing or maybe I have bad information on this site so double check on the internet via a map to make sure the given location is listed properly. Also, in time, a location could have been torn down. Have a fun time and take lots of pictures as everyone that is into this great hobby loves to see as many pictures of a location as possible to see how it has changed over time.
