I'm curious, considering the cost of Gatorade, Powerade, etc. at convenience stores, truck stops, and wherever else one might stop while on tour, how many of you bring powder mix along rather than buying bottle after bottle?

Today a 565ml (~19oz)(I think) Powerade cost me $1.12 with tax. A Gatorade container with enough powder mix for 6 gallons (~768 oz) cost under $8. Granted, carrying the powder mix would add a couple pounds, even if transferred to ziplocks - but the cost savings seems worth it, doesn't it?

This assumes, of course, that free water is available enroute.
