Trikes are a state of mind
More seriously - most bike paths are a total pain in the wotsit for trikes as the 'gates' and other structures meant to restrict access for motorised vehicles also tend to make things difficult for trikes too.
My Trike is less hassle with these than my loaded tourer or any of the trailers!
