For a really 'Hard Way Home' someone from Elkhorn NE (not us) has entered their Grenadier in the 2024 ALCAN 5000 rally. We have done this winter rally twice
2016 was 5,500 miles one way and 2020 was 5120 miles one way that included Tuktoyaktuk and the Aklavik Ice Rd. Temp got down to -40F, blizzard, 60mph winds and a -90F windchill. The 2024 ALCAN Winter Rally runs from February 21 - March 1 ending in Anchorage for the start of the Iditarod. Then you get to drive home from Anchorage!
