Carnegie Mellon University (engineering, music), worked in production for three years on Public Radio's Weekend America, reported on occasion for NPR, and now co-host an internet sports radio show.
Pro Tools, Shure Beta 87C, Sennheiser 416, various other mics, FTP software, Dropbox, MAC computers, a few different styles of speakers. Again, I was production mixer for three years on Weekend America, so the technical side is solid.
I've called Finish Lines from The Vermont City Marathon, to Bay to Breakers, Beach2battleship, Mountains2mainstreet (South Carolina), many more nationwide, etc.
I do pre-records for races that I am not attending. PSA's, sponsor announcements, etc.
