You won't need calls.Check WDFW's site for harvest stats and the regs to see what units have what seasons and how far you are willing to drive. Scout and hunt, public or nock on doors. WDFW has some sites you can also check, some require a reservation, some require written permission and some are first come, first serve.
Not sure of what gear you have. But GOOD waterproof boots are going to be your best friend. If your feet suffer, you suffer. By college student, I'm guessing you're attending Central. The mountains to the north of Ellensburg are home to the Colockum herd. They are hunted hard. There will be a lot of hunters up there, if that's where you're looking to go, be prepared for that.Gary
As stated above, you don't NEED calls but having a good diaphragm for cow calls is definitely a bonus. I would suggest starting with a simple single reed diaphragm and watch as many videos as you can. Practice whenever you have time, watching TV, driving, taking a dump, whatever. Bugle tubes are great and look awesome on youtube but a cow call goes a long way. Good luck out there.Cascade
Reminder to ALWAYS wear your orange. Modern rifle elk can get a little western so make sure plenty of orange is visible. Have fun and be safe. Let us know how you do
