  1. Stephen Stout Says: To Whom It May Concern,Thank you to each and every one of you that participated in any capacity to save the Beavers. I have worked and lived in Walnut Creek for many years. I never had a reason to visit Martinez other than business or visit a friend. This evening my wife went out with friends so I thought it would be fun to visit my friend Kevin Bacon who lives in Martinez. My daughters joined me on the outing. After eating at Burlington’s(spell?) we visited the beavers and met several very nice people. I wanted to take the time to thank you for affording my family and I the opportunity of seeing animals in the wild. My daughters were able to walk away with a touch of nature and an experience that will last a life time. What a nice town you have. Again, thank you.
  2. Monty Says: I’ve recently been called to jury duty in Martinez. Can’t wait because I’ll be real early and try to catch a glimpse of the little critters! What an amazing thing to see. Thanks for this site and all the information.Monty
  3. Jean Says: The whole family has been seen in the last few days by a very diligent lover and videographer of the beavers. I’m so happy I’m dancing in the streets!!

my boyfriend and i decided to take a valentine’s day adventure from san francisco despite the rain and got lucky. just as we were getting impatient, we saw a critter pop its head above the water andheadtothe dam! it was around 7:30-8pm, he or she hopped up on top of the dam andwassnackingonsomething. we tried to get a better look with a flashlight (not smart) and scared the beaver away, but after a short walk we checked back and were surprised to see two beavers! can’t wait to come back when the daylight hours are longer!
