I really want to give my Russian tortoise an outdoor pen for the summer. I live in Western Washington and was wondering if the weather is okay to keep a tortoise outside in the summer. We get some rain and pretty mild temperatures of about 60-90 degrees. Sometimes it is a bit humid, though I'm not sure what the humidity is. Also, I have no idea how to make an outdoor pen. Preferably on the deck (has the most sunlight and available room)
