38 34 Messier objects unobserved. Many of these are open clusters I never got around to observing while they were out before, but will knock off when they come back around. The globulars, by and large, were also just overlooked while they were out. Some of them may have also been observed, but I forgot to note that I had observed them. For the galaxies that are left, dark sky site visits may be in order, but some things I never got a good chance to observe over the winter because I had so few observing times. Unfortunately that applies to a lot of the rest of this year as well. This winter doesn't look very encouraging either, but at least I've been getting better at this.
