C&TS 2017 Fireman School

Greetings! I read a whole lot more than I post, so I apologize if I am not a familiar NGDF poster.

I have not been fortunate enough to visit the C&TS since 1995 (I rode behind 463 from Antonito to Chama). It is time for that to change! I would like to attend the fireman school in 2017 and am trying to get my ducks in a row so I can go. Do any of you know when the schedule is likely to be released? I would like to request the time off from work as early as possible so I can plan ahead. I haven't had a vacation in years and I cannot think of a better way to spend mine.

Thank you,
Dave
