I collect it in a couple of 5 gallon buckets under the eaves spouts. Oddly, here it measures at pH 7.0 on the nose, in spite of my living in a large-ish city (Montreal). We have severe acid rain problems an hour to the north, but not here. I give it 24 hours in a 40 gallon, filtered on charcoal in a little fluval. A few times, I've skipped the filtration on all day heavy rain, with no problems. Pros - cheap as could be, clean water. cons - heavy buckets, irregular rainfall patterns (feast or famine), storage I don't collect for the first 15 minutes of a rainfall. I use snow in the winter, with equal success. - -Gary
