Are these Mule deer or Blacktail deer??

Help me out here guys....in northern California (outside of Santa Rosa) two weeks ago, I rode up the coast and saw TONS of deer feeding in the grass just a matter of yards from the beach. Anyway, got plenty of pictures of them but cannot figure out if they are mule deer or blacktail deer. I thought they were mule deer until I saw a hunting show on tv where they were hunting blacktail deer in the same area as I was in and they looked almost identical to mule deer. The first two pictures are of 3 bucks that were no more than 30 yards from the road (sorry it's a bit fuzzy---the sun was going down). The other pictures were taken with 10 yards and some as close as 5 yards. Since I'm in NC, I've never seen either of the species so hopefully someone can positively identify them...only wish they were as tame in NC as these were!

Blacktails !

Only the tip of the tail is black on a Mule Deer. What you have there are Blacktails. By the way they can cross breed and really screw IDing them up. With the size of a couple of those bucks, I wouldn't be surprised if that is not the case. Nice pics.
