Depends on the drink, ice can water down a lot of flavor so I don't
prefer it. I hate lukewarm water or anything unless it's meant to
be either hot or cold. I usually stick water bottles in the fridge
to keep cool. If I'm going traveling I'll use ice if a cooler isn't
avaliable. For some fruit juices I like ice because they can
sometimes be too strong and it's a double win to keep it cool and
water it down a bit.
