Loaded weapons welcome here.
1. Can I open carry?
Yes. You can also carry concealed without a permit if you are 21 or older.
2. Open carry in the parks?
3. Open or glove carry in the vehicle?
Yes to both, you can transport your firearms any way you want to, if stopped by an officer and asked if you have a weapon, you have to tell them.
If carrying, stay out of schools, government buildings and places that sell alcohol for consumption on the premises.
There is no enforced 1000' rule for schools.
Drinking and carrying is a bad combo, don't.
Be careful of reservation land, the rules there can be dicey.
I'm sure you will enjoy your stay, be safe!
