I went to WY last year and had to buy a strobe, I'll double check, regs change so much. thxYeah, both states allow thermal, but with some differences. In ND, thermal is good to go once deer gun season wraps—last year it was open 11/25 to 3/31. WY is legal too, but you’re right—there's some talk about using a strobe or ID light if you're with others. Always best to double-check regs each year, they can shift a bit. Better safe than sorry.
