Taking a trip.

This could be the bicycle used by the Swiss chemist, Albert Hoffman, who was the first to take LSD to study its hallucinogenic properties.
As the drug began to take hold, he got on his bike and tried to cycle home to safety.
It isn't Albert's, of course, but rather my circa1905 bike which I took out for a gentle spin. It doesn't do hills or traffic, but is a delight.
