At the start of our cycle ride, looked across Ft. Snelling State Park towards the airport. Followed the Minnesota River, then Mississippi to downtown St. Paul. Cycled back, mainly on trails on the opposite bank. Click through for an extra photo of a (potentially) high voltage eagles' nest.

However, the weight of the motor and related mechanism meant each arm needed to be reinforced to the point it became too bulky and exhibited excessive inertia. By contrast, pneumatic cylinders are light, and can apply significant force to a relatively minimal limb …
