It's 15 degrees outside as I write this. My landlord (God bless him) has the heat cranked up so it's a toasty 75 degrees inside. My tanks are holding steady at 82 degrees, but I do worry sometimes since they are next to a north-facing outside wall. I'm thinking of getting a spare heater just in case the one I have decides to die.
I'm off to Long Island this weekend and I hope to visit the beach! I love the beach in the winter. It's very peaceful - you just have to bundle up in layers and wear a mask and gloves. I especially like the patterns in the sand that are created by the wind and waves. In the summer, the park grooms the beach, destroying these patterns and whatever washes up.
