Many thanks for the comments.
The structures are very impressive but not always the quality of the photo (mainly the handheld ones when you realise back in the van that your shutter speed was less than the focal length - can't go back and take it again ...you're off) but these situations with low light and often times great contrast (a storm can sit in the sky with clear blue skies either side,another amazing aspect) need more than a point and shoot mindset and quite often there's a sense of urgency too,not usually time to check out the LCD images and Histogram and retake ,infact each year I go I have an improvement over the previous year in how I get two cameras with lenses attached (17-40 & 24-105) around my neck with a 70-200 and 1.4 X ( in case I need reach for tornadoes or cloud tops) plus lens wipes etc. in a shoulder bag to the roadside fence..and now a 15mm fisheye and hopefully a tripod...lol a bit ambitious to say the least. The guides will tell you that storm chasing and photography don't go together very well or even at all, it's no doubt why I often get so frustrated. Almost all participants every year are quite happy with a point and shoot, I'm usually the only one ,other than the guides that takes a tripod.The point and shoots these days deliver very good shots,I sometimes envy them that they just enjoy the structures and don't have the self-imposed pressure I suffer of attempting to get the best shots.
Ref. the bear and the cub, a good analogy really, that kind of situation arises most often with lightning and over the years I've experienced it too close for comfort on more than one occasoin-one of the nearest was at a railroad crossing last year and we were all out of the van and a strike came down barely 200 yards away, we heard it ..that would be mama bear I guess Lol. so we had to hightail it out..fast. To my knowledge no-one has ever been injured, certainly not killed doing this, the guys that run it have MA's and Bachelor degrees in meteorology and read the radar well and keep us safe, the problems arise when you get big storms near urban areas- OKC especially and when it's a weekend and the 'lads' get in their cars with their buddies and go after them and not always with road safety in mind.
Here's the TIV2 built by Sean Casey (who was with it) at the Sleep Inn Guthrie OKC May 23 along with the research team from OKC Uni.
