Big thumbs up for Cark and also Castle Kennedy. Visited both en-route / from Glenforsa . Nil fuel but great places to land and overnight.
LLR no real problems ............ wow! the extra 50 feet in height makes it so much better
Best advice is
not to stick to the middle....dial in the Manchester listening squawk and monitor radio.
Pity there isn't a dedicated radio freq for the LLR....that way you might have an awareness of other conflicting traffic.... has it ever been considered ???
