Hi from SF Bay Area

Where would the local PDs/county sheriffs be in those areas? And do they have K band?

They are all state 2 lane highways going to and from, traffic patrolled only by CHP. I think the closest actual police departments to Yosemite are pretty far away, in Fresno or Merced, depending on which way you go. Either way, you don't encounter them unless you pull off the freeway for gas or McDonalds. Just go with Ka, you're be safe.

Actually, funny story as my last trip to Yosemite I stopped in Merced on the way back home. Hot as hell, it was probably 108 degrees in July. My g/f and I pull into a mall that had a ice cream place, and 3 or 4 police cars come screaming into the parking lot, one of them almost crashing into my car. I guess someone shoplifted some underwear at the local KMart next door.
