Lots of them around here as well, depending on the time of year. Right now, I keep an eye out to see if they show up on the ice off of my place if it opens in spots. I'm on the opposite side of the bay though relative to the ocean so it's not common unless we go for a quick drive to walk the ocean side
When I was in my early teens, we had a younger seal who seemed to have broken away from the herd and took to sunning himself on the raft we swam off of. He became very curious and playful with us, often swimming loops around us as we swam underwater. Next summer, we didn't see him again.
I don't recommend that you just walk up to seals though. They normally can be very cranky creatures.
