Thanks for the info Kevin. Do you still live in Manchester?
Just moved there. Lived in the Eastern Sierra for many years.
I've not been bothered by marmots personally at trailhead, but at my home rabbits and ground squirrels were an issue for myself and my neighbors. They get into engine compartments, most likely seeking warmth, and can chew on wires. I had to make several repairs over the years, as did my neighbors. FWIW - moth balls didn't work, and automechanics in the area would tell you they're a waste of time. Decon did work over time to keep the population in check. I hated to use it, but didn't have any other choice.
Hope this helps.
