I would echo that. Yes, I am in the beautiful coastal part of B.C., but I know that back home in Revelstoke there's snow.
I would agree that times when there is not as much snow are very important, because then there is much more accessibility for people who have disabilities. Also, people who are living in rural and remote communities are better accommodated in the better seasons. I'm not sure that the height of summer would be so great, because kids are off school and people have vacations and so on. There are plenty of months in the year when snow and ice are not such issues.
