Did you tell the controller that you were IMC?? when 10 East of BIG at 2.4A??
Excuse my ignorance, but you were at least at an IFR safe level. How did you get into LM with no Inst approach or did the wx clear by then?
Althought he access for IFR stuff from the East isn't easy, were you offered another routeing? Or were you MADE to drop out of CAS? I take it previous to this you were airways?
