Lets not forget too that a bigger group of both fans and drivers of Mods, Stocks, and Hornets tend to show up in the 6-6:30 time-frame. See it every week really and have for years. Stands tend to be relatively empty looking until 15-20 minutes until hot laps when people come down from their cars and the later arrivals pile in. While several of the other non-sprint classes rapidly pile in as well at the pit-gate.
While I'm not a promoter, I really didn't understand the reasoning in pulling the plug that fast. I mean, it was one of those late afternoon pop-ups that tend to happen during these warmer days from late May into September. It only lasted what, 10-20 minutes and not all of it was even heavy either. I live just minutes from the speedway so I know how much it rained, and like many here have seen much worse and still ran. There are 2 divisions of sprint cars and they do have some equipment but I guess it was too much of a pain to bring it out to till up the track or ask the drivers if they wouldn't mind wheel packing and running in the extra moisture. Given the extra-moisture burst from Mother Nature I'm sure they'd be okay with it if it meant they can race. I'm sure the fans and drivers both wouldn't mind starting a little late too if it meant they could race. Being a regular night, which most get over between 10-11pm, a 30-60 minute delay wouldn't of been too bad given it was weather related delay and not dilly-dallying around.
But point remains there was still an hour till hot laps when the rains stopped (and let's not forget, some of this rain would of been the extra water put on between 5-6pm anyways). The sun came out after to help dry things out! Most of the sprints were already in the pits or just arriving, as usual. So during this hour, it wouldn't be unreasonable to get equipment out and/or get cars out there by 6:00-6:10 (since most are ready for engine warming by this time) to work it all in. Heck probably could even squeeze in a few groups of faster-hot lap style runs to blow off the top layer of crap before going into actual hotlaps at 6:40-7:30pm. Heck, coulda probably even had other divisions helping too. Sure their tires are much smaller, but every little bit helps. Can almost consider them similar to a push-truck in terms of efficiency really.
Safe to say most are simply upset from the lack of effort
Also, given that it was so late in the afternoon when it happened most people/drivers were already on their way or there. So it wouldn't of caused the usual "butt-hurt" of last-minute call-offs. When people do get upset is if it rains sometime between 10am-3pm and a decision isn't put out until like 4pm or later when the far-travelers are already on their way. Still, given how late it was, why not at least try? I'd rather see an attempt and fail than no attempt at all. And given how many people use Twitter/Facebook/IOW it wouldn't of been too hard to post a status that the event would be delayed-start to try and work things in and try to get the evening complete. Would it of lost some fans? Maybe a few, but by this time they'd be the ones in and around Bloomington itself. And if they're already paying attention to social media anyways and updates are given accordingly they can easily get there by the time hotlaps are started or complete.
