Picking a Half Marathon

So, I'm having trouble picking a half marathon. I have found three possibilities and each have pros and cons.  I thought writing them out in a post could help me decide.

Knoxville Half Marathon; April 3rd

Pros

-close by

-$60

- could run the parts of the course before the race to get used to it

Cons

-hilly

-earlier than the others= less time to train

Country Music Half Marathon, Nashville; April 30th

Pros

-later than the Knoxville Half

-pretty flat course that goes through downtown Nashville and Centennial Park

-Rock N Roll series which means it's a well organized race and will have a lot of people; they also have live music and other events

Cons

-expensive $90 if I register before the end of the month, although I think I found a $10 coupon

-would have to get a hotel room and pay for meals

Kentucky Derby Half Marathon,  Louisville; April 30th

Pros

-same day as Nashville

-would get to visit a new city

-cheapest @ $50

-course goes by Churchill Downs (the race is a week before the Derby)

Cons

-would have to get a hotel and pay for food and such

I'm not sure which one I will choose, but I feel like I need to pick one soon because the prices go up at the beginning of 2011 in a few weeks.  Decisions, Decisions, Decisions....

Also, I may or may not be running today because it is 25 degrees and looks like this out right now...
