I don't really explore as much during winter.
But I nabbed myself some new Pokemon today.
I caught a Heatmor and Durant.
I also trained my Sigilyph and Froslass.
And I rode on the Ferris Wheel with Martin (he's the trainer female players encounter there in winter).
I also picked up some TMs as well.
Yeah, Nimbasa City is where I mostly explore.
