I hid this one out there some time ago - but it seems to take me a long time to get motivated to submit these.
The causeway is a 4 mile railbed that used to run from South Hero to Colchester, across Lake Champlain.
The abondoned railbed is now a great bike path, except for the missing bridge, just north of this cache.
In the summer from May to Oct there is a ferry for bikers and pedestrians to cross the gap.
