Something to keep in mind is that in the RW temperatures can and do vary
quite a bit. Winter, even the dead of winter doesn't automatically
mean -30. I remember leaving Winnipeg right after New Years to go back to
Ontario for school and it was raining. I also recall -30 and colder in
January. Today's high was -23, tomorrows -18, Saturday -4. Now, in
Glorantha the weather may be less variable but I doubt it.
