Yes, in the beginning I had a mentor that I worked together with that has now passed away.

Primaries and secondaries are all different electronic devices. The secondaries are those that I haven't learned how to determine magnitude with yet.

I do throw in other things like ants, clouds, pops/cracks in the house, etc., but they are not the secondaries that I refer to and I don't keep from mentioning those things. But these are just indications as well that some type of quake, moderate or large, is in the near term future.
