Well, I (this is Mike) learn something new every day. Finding this blog option of Pbase will permit me to add additional information with my images from time to time, for example, shot details.
Here, I used my "older" Canon 30D with my 100-400L lens at f.6.3, 1/3200, ISO 200, +2/3 compensation at 180mm focal distance. I at times carry two cameras while photographing Snows, the other a Canon 40D with the 400L fixed lens.
Both lenses have their advantages and disadvantages - in this case, at only 180mm, the 100-400 came in handy.
This winter was a little more difficult, I had to leave one camera behind, trading it for a cane because of knee problems.
Cheers,
Mike
