The WWB a few weeks ago has had/will have more effect on the subsurface than this trade burst will because it is in alignment with the preexisting state before the WWB. Overall it’s not meaningful (especially not at this time of year).
I always thought you were a lot closer to the lake. I just checked where Harrison, MI is located on a map and its quite a ways away from LM. Are you just south of Houghton Lake?
