Great talk at lunchtime today (after the excellent cosmologist a month back) from an academic who went dogsledding in the arctic. Great photos, great story and a great theme (team management techniques she developed from her team of four dogs).

Of course, it can only leave you feeling disastisfied about:
a) your own presentational skills
b) your photographic skills
c) your vacation plans which don't involve anything more exciting than a train journey.

Day off tomorrow, though, so something to look forward to...
