okay i have a pretty big yard and i want my lighted deer to be in the middle and i was other things before that too so i have one 30FT extension cord plugged into our outdoor plug then i have another one coming off that with lights plugged into that (it has 3 outlets) now can i add another one to that so basically it will be 3 extension cords back to back with a couplew sets of lights connected on the way (maybe about 5 sets total and then the 3 deer)

is this safe or should i think of another place to locate my lights?
