I do. Until 6 years ago, I was able to take advantage of it.
I recall a bad cold wave around Thanksgiving one year, when the Great Lakes were still warm and ice free. A duct set up over the lakes and up the St Lawrence valley that allowed me to work K1WHS in Maine on 2, 222 & 432, along with VE2's from EN52 - well over 800 miles. And, 2M QSOs all the way to VE1. On 432, I was using a single 9WL yagi at 40' and 200W.
I also had a 'everyday' range of close to 400 miles on 2M troposcatter with a 5WL yagi at 75'. Well set-up rovers could be worked out to 300-350 miles on 6 & 2M. That's actually not too much different from what I see here in DM58. Unfortunately, many local rovers are just not set up for longer haul stuff like they were in the upper Midwest. They mostly have a 'work local' attitude. You would never see serious rovers in IL, WI or MN counting on loops for 6 or 2. The easily worked 6M rovers ran full size antennas, even if it was just a dipole or beam driven element. It made a huge difference.

Last week, there were several -days- of 2 meter propagation between Mississippi
and Ontario/Western NY, to the west of Dorian. Eat your heart out.
