What California has done is MEANINGLESS, since the US Congress has passed the FAA Re-authorization bill, which INCLUDES section 49 U.S. Code § 47107 section [22]; ‘…prohibits the sale of 100LL after Dec. 31, 2030…’
So, the comments on CA, or other states or airports are moot. The FEDs have put the stake in the ground.
100LL is GONE in Jan. 2031.!!!
