Day 3 Hint
Make sure that you’re home on the morning of Day 3 (at about 8-9 am). At that time, you’ll receive an unannounced visit from a stranger who will give you a useful tidbit of information.

Ice and the Hellcats
It’s been said that the most effective way to eliminate the problem posed by these pesky critters is to drive at them at full speed right in the middle of the road. This game of chicken will run them off the road, and allow you to pass.

Weather Hint
It’s a good idea to constantly monitor the weather by ducking into the weather station each day. The main reason for this is that venturing out on a 70 degree+ day can be very dangerous. After day 6, though, traveling to the airport on one of the hotter days gives you a good chance to record the ants’ noises.
