Always, always carry a machete' for this work and marker flags...
Go look see in the Spring and marker flag your stops, record in notebook how many holes at this stop.
Go back in Summer to your flags, to set traps and you have a jungle.
Check notebook how many holes at this site, so you know how many traps and stake you need to carry. Cut & chop path (where did this Sumac come from?) to den holes.
Dang, they dug two more fresh holes. Back to the ATV and get more traps and stakes...LOL
