depends on how large the boards are- maybe 2x4’s? 6” boards maybe? if it is 4” the tracks are really small, if 6” then they are a bit larger- I woudl think though a bear track would take up most of the board- but again, not sure what size the board is-
Looks to Me like 1x4, 1x6 and 1x8. Either way if that’s a Bear print it’s not from Yogi but possibly Boo-Boo based on board sizes.
I’m going with a Canine of some sort.
A composite deck board is 5.5” in width.
2x6 or 2x8 I’m going with 2x8
