Jeanette, congrats! It's sure to be fun.
If I may make a suggestion: if you plan on doing the SCBA/Fire training they make available, I would strongly suggest you learn to love life without air conditioning. In addition to physically working out (running, weights, etc), part of the problem with fires is heat exhaustion. Being more acclimated to hotter temps means you'll be more effective.
Many of the FF's I know in SoCal (where I volunteered for years) wouldn't have A/c in the stations, or use it in their cars, during the summer months.
