Biking on snow

The family just did a ski trip in Tahoe/Reno last month. Really not my type of activity. However, I have always been curious about riding a fat bike on the trails in the area and have been googling for the past few years. There are bits and pieces of info out there but this time I actually went in person to one of the places where one can rent a bike and ride: the Alder Creek Adventure Center for Cross Country Skiing at Tahoe Donner.  Too bad the snow condition on the trails were not suitable for fat biking when I was there as the snow cannot be too soft. The lady at the counter was very helpful and gave me this number to call (in the morning before you go): 530-587-9484 (or check the Grooming Report online) The cost is reasonable too: $19 for a day trail pass + $34 2 hour bike rental (if you don't have your own) Alternatively, if you have 2 or more people, you could join this tour which included instructions for snow biking skills for $90 per person. Both of them are in North Tahoe. I will try to find some info for South Tahoe and post it here. Most bike rental/tour shops mentioned they would reopen in the Spring. I think that's the popular time. I am looking forward to a snow biking trip some day.
