Same thing happening these past 2 days in Bakersfield, Ca. Some trails that were in the sky Sunday eve were still lingering 12 hours later in their same location. And today there are dozens of these trails hanging in the sky and dissipating out into cloudlike formations. My friend in Aubrey Texas has recently come down with a rather horrible congestion and skin rashes that she attributes to the contrails. Even with any definite cause, when I was in Texas this past weekend, her skin condition was very real.
