Hi, looking for something free to do this weekend with the family? We're (Loudoun Water) hosting an Aquiary Open House this Saturday, from 10–2. Walk through two floors of water-related exhibits. Water conservation, water reclamation, watersheds, archaeology finds and more. We have trails outside, but they're covered under snow so that part is totally optional. I'll be working the open house so stop by and say hi.
