Workout, is it worth it? ... hmmm

I am driving 40 minutes to workout, doctors orders, for maybe 40 minutes.   Is it worth it?
   My physical  therapist stated today will be my last required medical day of fitness because I have succeeded in rebuilding my core strength.   I was fighting muscle atrophy and won the battle.  ;-)  I will get a free 30 day pass to a fitness gym in a local college, but it too will be a 50 minute drive. 
   Oh just in case it is not understood,  both drive times mentioned above are for one way,  so double it and you will understand why I am wondering if it is worth it.  
    I can work out at home,  but who will hold me accountible?  Will I actually make myself stick to a routine? 
    Check back here,  I will keep you posted about what I decide and my progress.  You can be my accountiblity? :-D
