One more thing - although several manufacturers of rain barrels leave water in the bottom of their barrels to weigh them down and keep them from moving, I'm paranoid of mosquitoes and we have far too many already. To supplement my screen - covered openings and draining within 5 days of filling, I filled the bottom 5cm with concrete - right up to the top of the pipe on the inside of the barrel. It won't evaporate, leaving a flight-risk barrel, and it'd be rough for larvae to grow in it.
