If you want to get into 30" mule deer, I would say your best bet right now is Colorado. I have seen many, many photos of very big mulies out of CO the last couple years, their mulie herds are STRONG right now. 20 inch mule deer really are a dime a dozen in Montana, and VERY western ND & SD. I pass many up each year, just cause I have been there done it, and would rather save them for next year than shoot another. For my money, if I was going to spend it, I would hunt Colorado. I dont want to spend it, so I keep searching Montana, and I will hook up eventually. Good luck to you, and let us know when you make your plans.
