Here in Finland we had a study whose purpose was to connect data of bolts from lightning detection network to damage on target and analyse results.
Of course this summer had to be one of the worst thunderstorm summers for decades so chances for getting lot of data were kinda "watered" by generally cold and rainy weather so data was limited to two dozen hits. But compared to number of cases studied before this that's big increase.
Results should appear in international lightning science journal during winter but here's presentation of them made for seminar in Sweden.

There's two really nice photos of tree getting "electroshock therapy" if text doesn't interest.
(getting bolt into 1/250s exposure... that could be called as lucky shot)
As sidenote conscripts practising on field were targeted by lightning three times on this summer while I don't remember how long it has been from single previous case.
