I walked with my Larvitar and got enough candy to evolve him all the way to Tyrannitar and to power him up a bit!! Never thought it would be happening in any near future ;) This was helped by hatching 3 Larvitars from 10 km eggs, which I had been collecting for a while until I got all 9. (The other 6 hatches were crap.)

Also, caught 3 small Aerodactyls (in addition to the one I already have), and enough Onyxes for another (hopefully better) Steelix. And more candy for my Rhydons and Golems are always welcome :)
