Kipling had it right (for once!):
A friend at a pinch is a friend indeed,
But a fool to wait for the laggard behind.
Down to Gehenna or up to the Throne,
He travels the fastest who travels alone.
I've always toured on my own and find it a great way to meet people and discover places that I probably wouldn't if I was part of a group.Plus I don't know any group that would have me...., but then:
"I don't care to belong to any club that will have me as a member".
