DO NOT go without a car. You will lose your mind without it. Being a brownbagger, sometimes the drive home (the long way) listening to Coultrain was more therapeutic than sleep.
Recommendation for NOT having to drop to Mike...Check in early on check in day, like way early. Even 9AM wont cut it. This will at least get you considered to the training company you were meant to check in for. After that, be physically qualified, be able to swim a 2nd class, and crush the PFT. That's how you not get stuck in Mike. Have fun with that.
