It is doubtful you will find hogs on any of the (limited) public lands East of 1-5 (Like the Bend area). If you know someone with several thousand acres over there, you are golden! I'm lucky enough to have some private land access on just West of I-5 in that area...and killing pigs there is still a time-consuming process. There are some outfitters that offer some very good hunts in the region, though.
Best of Luck, Jeff
