yeah i wasnt sure what the name of the gravel road part is. i just checked google maps, its called powderface trail. i whiteknuckled it on the gravel section. fun in summer on gravel, nerve racking in winter with ice and snow. saw a few people loking for xmas trees too. even driving out hwy 40 was nice. the big hills out that way are pretty cool. nice change from the usual ones on hwy 1 heading west.
and yes Dom, the trans rockies mountain bike race is insane, one of the hardest with world currently has. a good friend has competed a few times. the route changes a little each year. this past years event supposedly went through K-country, not sure where though. no vehicle driving on the bike trails of course but powderface trail at the end of 66 from 22x is a normal road in summer. but alas, it is closed for the winter. check google maps for all the back roads.
