Duncan's 5 Favorite Things To Do in Summer:

1. I love to run Scotty's Trail up Aspen Mountain (yep it's as painful as it sounds) and take the Gondola down...before work.  It's a long and tough alternative to the Ute Trail. 
2. Mountain Bike anything!  Smuggler - Lollipop - Iowa Shaft - Hobbit - Sunnyside is an amazing 20-mile loop!
3. Tuesday Cruiseday - A casual Tuesday evening ride starting at Aspen Brewing Company and ending at Smuggler Park for the sunset.
4. We-Cycle around town.  If you're showing a friend Aspen or taking a date out to dinner...WE-Cycle!
5. Bike the Rio Grande Trail from town to Woody Creek Tavern for the best margaritas and fish tacos outside of Baja.

Duncan's 5 Favorite Things To Do in Winter:

1. Breakfast at Bonnie's on Aspen Mountain - The oatmeal pancake is second to none. 
2. Cross Country/Skate Ski to the Maroon Bells.  When do you have the Bells all to yourself?  After the 7+ mile cross country ski from T-Lazy 7!
3. Skin up & ski down - Morning or evening, and definitely under the full moon!
4. Cloud Nine - A big surprise here, but go have the time of your life at Cloud Nine on Aspen Highlands...it's the best after hiking the bowl.
5. Hot Tub! - I won't tell you where I go, but Aspen is full of accessible hot tubs!
