We would definitely have a conversation about this. Sometimes I use hot laps as a chance to check out the souvenir stands or just sit some where out of the heat. I would also be upset if anyone pulled my blanket up during the heat races. Typically I am always there foe heat races. However last year at Lawrenceburg I was sitting under the grandstands during the heats with my pregnant wife. It was just way to hot for her in the stands. However once it cooled off some we were able to return to our seats and enjoy the race. I dont think anyone should take more space than what they need but you need to take into consideration people's situation before you start ripping up their blankets.
