The International Society for Individual Liberty (ISIL) is holding their annual winter retreat conference in sunny warm Phoenix, Arizona,  January 8 - 10, 2010.   [Note: there is an optional fourth day event on Monday.]
From their website: ISIL is a network of individuals and associations in over 90 countries dedicated to building a free and peaceful world through the ideals of free markets, social tolerance and individual responsibility.

Our philosophy of liberty, which is catching on world wide, is called Libertarianism.

Speakers include: Dr. Nathaniel Branden, Mary Ruwart, Carol Ruth Silver, Jan Narveson, Rodney Long, David T. Beito, Mimi Reisel Gladstein, and a heck of a lot more.

Their schedule includes the speaker's topics.

Full registration for all three days is $520.  That may seem high to some, but I know they eat well, and get this, it included the price of a shared double room at the Radisson Hotel, Airport North, Phoenix.  If you want a private room there is a supplemental fee.

There are several registration pricing options and IMHO some sweet deals.

There is provision for student scholarships, and a $125 special open to all of all Saturday speakers and lunch and dinner.
