Storm above Glencoe

Mixed weather today, started very wet with a temp of 7 deg C. Sunny spells later but colder, finally when I took this hailstones and 3 deg. I confess to a car window job!

The main dilemma - mono or colour, which do you prefer? I started off thinking colour, but after a while the mono grew on me and I think has more drama, but like all of photography - a matter of taste. Voting time!
