Crazy. They practically live in that spot along the Mare Island San Pablo Bay Trail. What’s the big deal?! Deer were thought to be extirpated from Mare Island by the US Navy, some 50+ years ago. They are still rare sightings. Anyone want a better view?! Fix or replace our nonprofit’s broken phone!

So thrilling to listen in on coyote families yapping and barking, Mare Island San Pablo Bay Trail tonight. Yes, I’ve returned.

Last night leaving a friend’s apartment, I was beyond delighted to meet up with our Mare Island Shoreline Heritage Preserve beloved(mostly) late dog, Nitro, reincarnated in this darling 6 month old puppy named Lok. ❤️❤️❤️🐕🐕🐕

Daily proof that I am safely outside our Mare Island San Pablo Bay Trail after sweeping the parking lot, all clear and locking the gate. 9/29/2026 thank you to our Mare Island Shoreline Heritage Preserve wildlands community and good night.

THIS is what “suspicious activity” looks like! I’m so proud that I snuck this video in last Wednesday, September 23, 2026 just minutes before I was arrested for unknown reasons by the Vallejo PD in the process of locking up the Mare Island San Pablo Bay Trail. If it is the city employee I think it is, he told police dispatch, according to a police press release that “this” was suspicious activity that appeared to be casing the property to steal copper. Haha! I think the old saying, “when you assume, you make an “ass” out of “u” and “me”, applies here. I paid the price with an arrest and 12 hours in jail and a concussion and other medical conditions. It’s just a matter of time before the price of engaging in this police brutality will cost them more than it costed me. In the meantime, I sincerely hope you are informed and inspired by my video. And that your heart is moved by this precious part of our Mare Island Shoreline Heritage Preserve history. These guard shacks are the original entrance to our wildlands park. Imagine with me, their return to “active duty”. Myrna Hayes

What’s not to love about NBC Bay Area and Reporter Jodi Hernandez sharing my story? I thank them and other news services and thousands of my friends.

Right after they seem to have “sandblasted” the ped/bike sidewalk. Hm.

Simply resharing the details of our upcoming Napa River Fall boat trips with Dolphin Charters We have a rather tight timeframe for you to register and load up the River Dolphin with delighted passengers. You are who I’m talking about! With diesel prices at an ALL TIME HIGH, we really need to honor our hosts and “fill-up their fuel tank” with a full boat!! Details in post.

You’ve been going CRAZY!!! WHERE, WHERE is there more info about registering for those boat trips you mentioned a month ago, Myrna Hayes????!!!

My beautiful and lovely friends who own and operate River Dolphin, Dolphin Charters, have A LOT going on right now. They have just arrived in WA State to reset their ALASKA cruise boat for the Fall-Spring. So, I was as frantic as you have been, to learn where our Annual Fall trips are. Right here.

Please call 510-527-9622 to reserve. They are out of state! Want a call back? Questions? Call/text me 707-656-7852. Dm me, too.

I promised some GOOD NEWS! Delivered! Please share. Let’s fill these 2 trips. With the price of diesel fuel, they sure can’t afford to run a half empty boat for 3 hours x 2 days. This is really a labor of love on our parts. We LOVE YOU! Come aboard, will you?!
