It is clear that people who are interested in weather phenomenons and who can't get the strongest storms will find a way to make some outstanding shots with smaller storms.
The amazing Christophe Suarez's lightning shot could be taken from a small storm that produced 10 strikes, then died, but he got them!
It is clear that most of the time, you guys will probably sleep in front of our thunderstorms here in Quebec, but most of our population don't understand the difference between an hurricane and a tornado, because they just don't care about what they'll never see. There is only a couple of tornadoes per year here, and when it occurs, if you watch the local news, they will talk about a "mini-tornado", even if it was an F2 tornado. Why? Because for them, tornadoes only occurs in "Twister" and maybe in a "legend" about some real tornadoes in the US plains.
Anyway, I wanted to say I spoke to many french people from Europe, and there is real chasers. The problem is that they have to chase only with their eyes. There is no real good data available. Chasseursdorages.com is a big community, and they are proud of their shots, but most of them agree that their dream is to chase on the US plains.
