Boston --> Princeton Junction

What is the least expensive way to get from Atlantic Union College, South Lancaster, MA to Princeton Theological Seminary, Princeton, NJ? That is the question that I spent hours tonight trying to answer. Yes, I have literally spent hours on this matter and yet I still lack an adequate answer.

I suppose I really have two main options. Option #1 I drive. Option #2 I take Public Transportation.

Let's break it down- option 1: I can drive down which will be about 5 hours of nonstop driving. I'm not a huge fan of driving. I will spend approximately $13,920 for gas. Plus the cost of tolls. Or take about 15 more minutes and avoid toll roles. Based on my status as a poor college student I would naturally avoid toll roads, but that still leaves spending money on gas!

option 2: This could break down a couple ways:

• The totally independent way: I pay for parking at the Leominster station, take the commuter rail to Boston, get on the T, grab the cheap Chinese bus to NYC, hop on the NJ transit to Princeton Junction, take the shuttle to Dinky Station. I'm unsure of the cost of the shuttle. Without the potential price of the shuttle that would be around $49.
• Ask someone to drive me to the commuter rail at the butt crack of dawn. That would save me $9 so its around $40.
• Ask Scott if I can go with him into work. He works right next to the riverside station on the green line. I would hop on the green line, switch to the red line, grab the bus to NYC, then the train then the shuttle. That brings it to about $32.

I suppose the benefits of driving is that I am pretty much on my own schedule.

The benefits of taking public transport would be I don't have to drive for 5 hours straight. It's better for the environment. I don't have to freak out about the prospect of driving anywhere near New York City.

Can I just say how much I hate hate hate hate hate hate being a poor college student. Yes, I hate it that much! How am I supposed to be able to afford to visit seminaries? I'm sorry, did I mention that all of those prices are 1 way!!!!!! ONE WAY!!!!! so double it, and that's how much it would cost me total. I can't find anywhere where I can calculate how much the tolls and gas would be so I am trying to make the right choice. GRRRRRR!!!!!!!

Help?
