When I was very Serious about snowboarding, the days that were pure powder and sunshine were blissful and meant for nothing short of maximizing joy. The not so good days, however, were designated learning days, so that there was always something to be gained. Ice and rain were perfect opportunities to practice riding goofy; fog was an excellent reason to play in the half-pipe.
One of the things I love best about running all over this city, is that you get to check out neighbourhoods and pathways that you would have never noticed normally. I love the seawall, but I try to mix it up a bit, because I also love running down streets I've never been on before.
