I have been noticing positive changes in the Manassas to Culpeper route 28 stretch recently. I picked up Band 41 out in the Midland area this week and observed seamless hand offs between all three bands as I traversed down 28. I actually flipped to band 26 in a spot where my LTE almost always drops back to 3g. The band 26 signal levels are still on par with band 25, so I am hoping there is more optimization to be done, but it's improving...
