Probable mountain lion sighting

Last evening Ed, my spouse, was walking up the trail that starts at the end of Park St. in Montara - he looked towards a noise in the bushes and saw a very long, large, tawny animal fluidly move away in a considered manner - quickly, but not in a startled fashion.  I won’t say it was a mountain lion - but I can say it was too big for a bob cat; to smooth for a deer or a dog.  I will say I will probably get some pepper spray to carry on future hikes up remote trails
