Driving; There is some road construction down to one lane if coming from the North around the Auburn area. There have been accidents due to this. If someone wants to avoid this issue completely, you do have a few options, even though they aren't on the highway. Coldwater road by the venue (one major street west) is also State Road 327. Anyone can get off at either exit 340 Ashley/Hudson or 334 Waterloo/Kendallville, and head west to 327. Drive time might be longer than on the highway, but no construction issues to my knowledge if that is your choice.
Weather; It is supposed to be 20% chance of rain on Friday high of 44F, and possibly hit freezing (29F) over night. Saturday Sunny high of 55, no rain.http://wane.com/category/weather/
