I dont know about sage rats in Bend, those are the little guys, but I know for a fact Bend has some big ol fat rock chucks. They failed to tell ya that!!! Uh huh, trying to save them all for themselves.
There everywhere down there. Even out in right field, no seriously!! When I was in HS and played baseball, we went to bend and Mt view and we had them rock chucks running all over the outfield. I couldn't take it, I was going nuts!! They were as big as house cats. Oh yah, I was envisioning the 25-06 w/85g NBT's at 3600fps, ha ha.
I"m pretty sure all the good chuck shooting is on private land though. So good luck trying to get on it unless you know someone...As with anywhere.
