On weekends, and most week nights, after the kids are in bed, Mike and I spend time on the deck. Weather permitting. Syracuse won the Golden Snowball again this year, with a total of 149 inches of snow. So it makes sense that we try to be outside whenever possible when it's nice out!
Last summer we started taking bike rides when the kids were in bed. Don't worry, we take turns! We live down the road from a small lake, and there are walking trails to use year round, they are plowed in the wintertime, which is a bonus. It's so nice to just coast around, enjoy the air, the sky, and the quiet.
We even make our guests do a lap if they happen to be over during bike weather. Everyone except my sister, who is so short, her feet can't reach the pedals.
