Once again, fall in Colorado has shown how very bi-polar it can be. One day the temperature can be in the upper sixties, and the next day can be thirties and snowing. These images demonstrate that, since they were taken on two successive days in early October. For me, one of the things that heralds the arrival of fall is when the Canadians invade (geese that is), so I took the telephoto lens and shot some waterfowl, Mallards and Canadian Geese.
