You can get a bull tag in OR for 2025, apply for a decent unit and when you don't draw pick up a OTC bull tag and go hunt in one of the OTC units in NEO. We have great hunting and I doubt there will be any OTC tags in the near future. You don't need anything special to hunt elk and rifle hunting is way different than archery and requires a little better gear since it is typically in the snow.
Idaho will also have some returned tag sales later in the year but IMO most of the tags that will be available during those return sales are going to be similar quality to OR OTC and ID is way more rugged terrain. Elk hunting is pretty easy, you just need to learn to blow a bugle tube and cover ground, elk run in herds and are pretty easy to find at night during the rut if you're quiet and listen. You may be able to find a mentor on the forums, I've met plenty of guys on here and other forums who have ended up being hunting buddies. The biggest thing that is going to make a difference is going to be time in the field, if you plan on coming out plan on two full weeks at least, planning for a week (5 day of hunting) just isn't a lot of time when trying to find where the elk are and cover ground.
