Few questions about extension cords, some of this may be self explanatory but I want to put it out there just in case there are details that need to be known about the different subjects, ie don't don't do this or don't use these. OR these are great or I found a great thing to do, this is how... Basic questions... Where do all the extension cords go to be hidden? Especially with roofs and what not? I understand that you can connect lights together but you have to get a power source to the lights themselves. How do you handle this both on the house and in the yard? I am thinking the house they get ran in corners and held in place with tabs? And the lawn you could probably easily "bury" them in the ground maybe a long driveways and sidewalks, or just using you finger to poke them in? Or do they typically just lay in straight lines as to keep it looking neat?
