If you're going through Portland, OR, there's a must-see store called The Wet Spot Tropical Fish. They're the biggest on the west coast and have everything. Literally. Including ADA Aquasoil.
"One day...one day, this path will lead us to the White City, and the tower guard will take up the call: the Lords of Gondor have returned!"
