Outside Santa Fe Bike & Brew Festival. Add in the season opening of the Big Mountain Enduro race series.
I have been able to attend part of both of the first 3 festivals. In 2014, I tried riding a couple of the group rides, but the 10 miles and the altitude, were just too much for me. Had a nice time at the opener with the brew and hand-made bike show.
Last year, it was cold and rainy. Braved the rain to attend the brew tasting & bike show, but skipped most of the other events - played "tourist" instead.
I have been debating if I should attend this year's festival or go to the Celtic Festival in Albuquerque. If any of my Omaha friends are racing in Santa Fe, I would probable opt to the bike & brew festival.
