Daytona Roar before the 24 - a practice session

Went to Daytona over the weekend to watch the Roar, a 3 day practice session for the Daytona 24 Hour race at the end of January. I try to do this every year. Very nasty weather there. Bear is right - Water freezes at 45° here. In the 30's both Saturday and Sunday mornings. There are 3 official classes of cars entered in the WeatherTech Sportscar Endurance series; Prototypes, LeMans Grand Touring, and Daytona Grand Touring. The Prototype class has 2 sub-classes (my term) DPi (Daytona Prototype international) and LMP2 (LeMans Prototype 2). I could further explain, but even I find it tedious. After the Daytona 24, the Sebring 12 Hour is next.
Some Examples:

LMP2 Oreca (Jackie Chan owns this one):
