Wow. Tapping maple trees. I like the outdoors, so to me that sounds like something fun to do witha friend.
I spent several hours yesterday doing a local saltwater tank tour. A number of people from a local chapter of the Greater Iowa Reef Society club went around town to look at people's tanks. The smallest tank was 75 gallons (being replaced by a 180 gallon that was just getting set up), and the largest was 250 gallons. The 250 gallon tank had a 120 gallon "sump" tank attached for filtration.
It all made my 120 gallon look tiny.
