Hello.  I was looking for the cheapest way to travel between Denton,
TX, to Austin, TX.  I live in Austin and my girlfriend is going to
college in Denton (outside of Dallas).  I am not sure of all the
different travel methods availible.  What would be my different
options (besides flying), and what kind of prices would I be looking
at?  Worst comes to worst and I have to use my car, any tips?

Thanks.

Perhaps car-sharing? Publish an ad in your local Craig's List (and
similar boards, also an actual ad at the college you're attending)
that you're willing to drive people to Denton (or back to Austin) if
they'll share your expenses.
