I wanna talk about this year's DX season, because it's been pretty interesting. This season has been hit or miss, because this year seems like we've had less skip than previous time. While we have had some tropo openings at least, there have been less openings of skip. Starting in the end of May, Skip was more present in the south, and everywhere else, but the Midwest. Des...
