old areas, i used ambush for wt, mulley deer in the morning and evenings.
if they don't show up i change tactics and go after them.
starting few years ago, with cwd on deer, they tend to change behavior, so ambush is not working all the time.
you start seeing big bucks between 10-11am, 2-4pm, exactly when you are relaxing between morning and evening hunt.
in week days - mo-fri, not a problem for ambush, but on end of the week... notca chance on some areas.
i have to walk deeper from the main roads to be able to fill my tags.
