If you're worried about fundamentals do a class to refresh the basics, but don't do it with a fly by night company. You could also do the online training Frank has here. If you can't find something local and want hands on, your could take his classes if they have not filled up. You could also try to get into a K&M or Altus/Core PRS based location and take a class.
A different path may be benchrest since the 1k BR class at Williamport is just up the road from you and you can get 600 and 1k experience. Granted it's not PRS but I guarantee you will walk away learning a lot. You might even be able to access that range for training as well. Ridgeway is a haul but another 1k BR. They might have options too and they do have the benchrest silhouette matches which look fun, so you might be able to practice there too. Closest PRS is probably Peacemaker, off 81 west of Inwood. I can't honestly recommend a class there after the one I took, but you can go try out a match there when they start back up on the spring. There's apps with all of the nearby ranges. I now of 2 1k ranges in WV over never Clarksburg / Fairmont., both BR but they do other shoots as well. I think there is a 600 or 1k on the edge of Ohio and another 600k or 1k in Delaware.
