This is what my son was doing this afternoon. Mountain biking at COP.
I was getting ready for our Europe trip and just bought light hikers in anticipation of the Alps and Cinque Terre (Italian Riviera hill towns). We all have lightweight clothes and have done extensive research about airport security, as we are only taking one carry-on bag each (total luggage). I regret that we have to connect in London, as Heathrow is at high alert right now.
In the meantime, we are packing, cleaning, gardening and paying bills so that everything is in order. Three more sleeps.
