I am headed out to CO on my first ever archery hunt there and wanted to know form U guys what can U use for a case for your bow that meets all regs for CO. Can I use a soft case or does it have to be a hard case. Does it acually have to be locked or just closed up. I am just thinking about it for my 4 wheeler and what is going to be best way to hual my bow to and from hunting grounds. Thanks
