Im unsure how tall and how wide to build these. Also whats the rule of thumb for how deep to sink vs how tall of a condo to do these? Im sure conditions will vary but Im new to this and would like to create a hot spot for me and my 9yr old son to make memories at. Also Ive been told by some fellers that have been around awhile to bait these spots with creme corn. Anybody do here do this ?
