I'll most likely participate in beta if invited, or if there is an open beta, so it'd be fun to be able to try it with other CGA members.
Don't really intend to leave GW2 any time in the forseeable future, though.
Sparkling water with a spoonful of juice concentrate of choice is also good. If carbonation isn't a problem. I like something tart like cranberry or pomegranate.
That reminds me of this last summer. At my sister-in-law's wedding they had big containers of ice water with various things in them. I'm used to things like oranges, lemons, and limes, but one had cucumbers and was very tasty.
