Botanical gardens

So today I walked from the hotel to the University of Coimbra where I gave the second all day workshop (a repeat of yesterday's one with different participants). I then got a train to Porto, taxi to the airport, and then had a three hour delay, meaning I didn't land until 1am and was home by 4am.
Anyway, the walk to the uni took me through the Botanical Gardens, and the weather was a bit british at the time, but I can image how lovely it would be to spend a warm summer's day here. The workshops have gone very well, with good participation. It's all been a bit hectic though and i haven't really had a chance to see anything of the cities I've been in.
