In person is the way to do it! Apply online, follow up with a few phone calls, make or try to make appointments, pack your interview clothes and your seabag and make your way south. I spoke to lots of nice folks that are drowning in emails/voicemail applications. Two of them offered me positions and chose the better fit for my situation. The jobs are available! Be warned that the medical/physical is failing a high percentage of applicants. Hope this helps!
