Used to be a lot of WP in the Simco Rd area south of the freeway, , but it has been quite while since I was there when WP's were out and about. Last year we saw plenty just East of Mt. Home along 84, they were running everywhere.
Yes, shooting will begin soon, we have seen a few west of Boise, but they will not be out in force for a few weeks, and we usually wait until they are finished having young, Will be soon, then until June or early July depending on the weather.
No season or limits, BLM maps are a good thing to keep you on public land where permission is not needed.
Hope this year is as good as the last few have been.
