Karting.

I took the terrible two to the gokarting track/leisure park today. Luckily they opted to ride the karts first, as after entering the park and settling down on sunbeds to eat our picnic, the heavens opened: huge lightning flashes you could actually hear sizzle, with simultaneous deafening thunderclaps. All the Spanish and German tourists ran inside at once, but being British we stoically huddled under a beach umbrella waiting for it to pass. It didn't, so we had to do the (very wet) walk of shame past the amused masses sipping beer inside. Apart from that, a good day.
