You can select specific activities from the recreation pages list.

Fall is lovely — sunny, crisp, and dry. Winter is generally bright, with daytime highs in the 40°s or low 50°s. However, cold snaps can plunge the temperature into the negative single-digits. Spring is often wet and green, with the occasional snow storm possible through May.
