I just hope your log appears natural enough to suit the canines! I prefer to plant a BIG bundle of marsh grass or weeds out in the opening where it is visible for a scent post, with one or two traps set at it and an appropriate scent post lure applied to the grass/weeds. Tracks are brushed and/or smoothed out the best one can and then a light snowfall will put the finishing touches on it. If one just lets the snowfall try top do the sign irradicating job, there is still going to be a lot of unnatural indentations in the snow where the trap was set and of course the tracks leading up to the set. Good luck...hope you get 'em! If you don't, you will still learn a lot from this experience. Snow is a great teacher as to how animals approach and work sets. Ace :-)
