I did it and am still doing it (to an extent), in the PE world (all while hopefully starting up a ski co. as well). I agree with a lot of these guys, I'll tell you first hand its a grind, but stick with it. in the long run you'll probably be better off having the IB background, at least for a little bit. put in enough time and hopefully you'll be able to choose when and where you want ski and not have to report to anyone.
not sure what type of IB your doing, but maybe you can find something that has a connection to ski industry...a tech. connection?.
the way i do it is, you pretty much pack up Thursday night and as soon as the bell rings on Friday try and get out the door. but you're going to get to the VT, NH, Maine area late at night anyway so no real rush, if you can bang out something that's due Monday AM, get it done, it makes monday that much easier.
Also helps if you have a place to stay.
One thing i can say for certain that i learned doing this... days don't matter, it might be cool to say i got X days, but just have fun out there when you can get out.
if you want to chat off-line happy to help.
