Thanks for the replies, gang.
I probably won't do both days of the event. So, the question is... which day should I choose? Saturday, where things might be a little more casual (always a plus) and I might get in more runs? Or Sunday in the more competitive environment to see just how much of a dent I can make in CSP?
And, yeah, I think I-4 & I-75 is close enough.

Should be 40-45 minutes from my house depending on traffic.
