Totally agree with you, i run a weather service here in remote Aus and having the knowledge of storms has saved my hide more than once for sure. Was caught between a fire storm after some intense lightning stikes, watched it jump the hwy and burn across in a matter of minutes, we had no choice but to gun through it once the winds shifted, scariest moment (my wife didnt come storm chasing for a while after that)
Whilst we dont deal with too many tornadoes we certainly get some of the most spectacular desert thunder storms and cyclones in this area. I really want to do a Tornado alley run (im sure you have done this a few times) but not as a tourist, just with an exp person and some raw photography.
Also YES! we have this issue here to, every dang bit of land is privately owned these days you really cant go anywhere without permission or heavy restriction, public land is becoming increasingly scarce
If you come over for a Tornado Alley Run, be prepared for incredibly long drives across monotonous tracks of land with no action. Storm chasing is like how some of my friends describe their jobs as cops/firemen.......days of bordom followed by a few minutes of intense adrenaline rush......then back to boredom again. If it is a slow season you may not see much.
