So Tuesday night Tam Lin and I are approaching the worst stretch of the Dr. Fisher Road. It’s not quite pitch-dark but close.

Up ahead are red brake lights. They aren’t moving. This is unusual.

When we come up next to the brake lights, I see that they belong to a West Tisbury police cruiser with no one in it. This is even more unusual.

Then I glimpse through the trees the front end of a white box truck, maybe a 12-footer. I begin to get the picture.

At the back end of the truck, through the gloom I recognize my buddy from the diversity task force, Officer Brad. I hail him through the thin line of scrubby trees — Tam and I are on the path close to and parallel with the so-called road — and ask if someone was navigating by GPS.

Affirmative. They’re waiting for the tow truck. Brad admires Tam, who of course has to go say hi. I say I hope the tow truck shows up soon, Brad does too, and Tam and I hang a left on Pine Hill and head for home.

I posted the above on Facebook. Among the commenters were a couple of FB friends who are real-time neighbors too. We brainstormed some appropriate signs to warn unwary motorists before they get stuck:

• “I’d turn back if I were you”
• “Abandon shocks, all ye who enter here”
• “GPS is junk here”
• “WARNING: GPS doesn’t know a road from a path through the woods”

I have photos of this particular stretch of the Dr. Fisher Road in all seasons. Here are a few.
