i made some fake tipups and after i had my 5 or 6 holes drilled , i would put 1 in each hole to mark them so that if some unwanted person came by, they wouldnt just stop and invade my holes!!!! each 1 was made with 2 equal sized pieces of wood secured by a nut and wing bolt in the center. all 5 or 6 fit into a pail and the inconsiderate sobs would bother me a lot less. i had 1 walk right up to me and start fishing 1 of my fresh cut holes. he even moved my marker!!!!! i said hey you could at least ask before you try and crowd me out. his reply was o did you drill that hole? you can imagine my reply,lol. he wasnt in the area long after that. rude idiot people, man you got to love them. tight lines and keep drilling and icing them tasty gills. big dave out
