[DL] Campaign starting help

[Jon Mollison <jonmonster@netcarrier.com>]

Okay,

So I'm gearing up for a new campaign that I want to run much like the
X-Files TV series; one major plot thread that runs through certain
episodes but other episodes have nothing to do with it.  The first
adventure is where I'm concerned.

It all begins with the PCs barely escaping from a tough band of law
enforcement officials after a brief fight - officials which clearly
outmatch them right now, but maybe after som etimne to hone thier skills
the PCs can go after these particular baddies.  But I'm hesitant to run
such a railroading adventure to kick off the campaign.  After all, since
my plan is to have the PCs run for the hills, we all know that's the
last thing they will think to do.

While I'm generally against railroading PCs in this case the ends might
justify the means.  I suppose I could just have a dying friend pass the
tale and the quest onto a PC, but that means one less adventure to play.

So, any ideas on "gentle" methods of railroading?
