We (Skylands Asatru Fellowship) don't do a blót for Midsummer, as we follow Snorri's calendar from Heimskringla. The tribe and friends got together very informally, feasted on hot dogs, hamburgers, and sausages, and spent the night around the fire drinking mead and talking. One person read a prepared poem about the day, but mostly it was just good conversation. A few of us did jump the fire, for luck.
All in all, I can't imagine a more pleasant way to spend the day.
Here are some pics from around the fire. Unfortunately, I didn't think to take one that included everyone; we had about a dozen people, all told.
