I haven't seen nor heard any mention of anyone caravaning up on Friday. Is everyone going to go it alone?
There are some long uphill stretches in the event. As a suggestion, you may want to remove your thermostat when you get to Burnsville. Also, if you have AC, disconnect the cycle switch on the AC accumulator so you can activate the AC button to cause the cooling fan to run, without putting a load on the engine. The weather up there is forecast to be in the mid 70's and partly cloudy. With 75 being the daytime high, it might be a little cool at night, so a jacket or sweater might be in order.
