No such luck as perfect fox time, foxes are always out there, put the time in learning the ground during all the different weather climes, wind, new and available food sources.
High moon they skulk in the shadows looking more, wind & rain in the fringes of woods, they just adjust visit routes to poss food hot spots and look to find the crossover points in their night travels
Couple of things I always keep to, go in quiet with the best breeze working for you and don’t give them a reason to be looking for you, always leave the same quiet way, every visit learn the ground and enjoy the time
