Absolutely loved the video.
Captured the essence of friends and fun. Great job.
I would like to second the suggestion about getting some mountain info in your clips. Your memory will begin to fail you as you get older. It sucks sometimes when the dates and times begin to blend together.
Just something as simple as including a shot of a base sign showing the mountain trails with maybe the year written in the snow. Simple, yet effective.
Great job overall. Well done.
