Up and Down and Up (and through the snow)

What a great day of i3 mountain driving! We left the car in Boulder overnight Wednesday as it snowed a decent amount in-town during the day, we weren't sure how much snow would be up at home and, since we needed to come into town on Thursday AM at the same time, didn't see the need to both drive. It was probably a good idea that we drove our Xterra home that evening as there was about 8 inches of snow on the ground at our house and the mtn road literally hadn't been plowed all day.

Then we come to Thursday. Zippy sat in the cold all night but the charge hadn't dropped at all when I began my drive to work (rolling terrain). I fully charged it (as full as L1 can get) while at work. At the end of the day I picked Laura up from work in Boulder and we headed-up the mtn. The road was plowed by this point, but a mixture of sand and ice. The i3 tires performed admirably per the usual. When we arrived at the base of our narrow, twisting, uphill, gravel driveway I was skeptical. There was at least 6 inches of snow that had now been sitting for 24 hours along with a small bump at the entry from the snowplow. Our neighbors who also use the driveway with their two large 4x4s had cut some tracks, but they are far wider than Zippy's nimble stance. At any rate, Laura was undeterred. I hit the accelerator and we shot right through the snow, around the corner and into our garage - what a victory - I shouldn't have doubted!

My elation was partly due to the fact that we were only going to be home for 10 minutes before heading back down the mountain to have dinner with friends, and then drive back home. I knew we'd be approaching the bottom of the battery by the end of the second ascent and so I'd be shoveling a long driveway in order to get to the charger if Zippy couldn't navigate the snow. 

The night ended successfully - once again Zippy showing his mtn prowess.
