[danwisbey85]

Sorry not getting hopes up here but...what if???
I whipped this up quick and came out nicely, audio from two real events and stuck together!
Ok imagine a tornadic warned storm and off they go!...well you get the idea! XD
I do not own either of the clips or picture, but hope you like!

I'm wondering what would a T-Bolt blower would sound like in the UK or any country using 50HZ AC instead of 60Hz AC assuming the pitch of the blower sound would be lower?
