Montana, Idaho, Colorado and Wyoming are OTC for residents. I believe Oregon and Washington both are OTC as well. Utah is too, but has a cap, so you have to get one right away.
For the record anything Werner says is suspect, he's never killed an elk.
Oh, and Werner, it's good to be me, I get a NR Native combo license every year for half of what the rest of the NRs pay. No way I'll have less than 4 elk tags this season and maybe 7 if I get lucky in the draws.
I'll hang pictures so you can live vicariously.
Idaho has OTC deer and elk tags for non-res but there's a cap on them. They put them all on sale online on Dec 1. This year, the demand doubled the supply. There were so many non-res online at the same time that it crashed the computer system.
