BCY: "....If you have a CSU and retract endorsement, then you can fly the C210 in command..."
Actually means: "....If you have cash you can pay for my trip too....."
OZZI_PPL what you want to do is a good idea if you are not confident but really your flight school should have covered it in the ppl syllabus.
I assume from this statement "....I'd love to hitch a ride with someone more experienced and learn the ropes so to speak...." that you would like to polish up on the CORRECT procedures rather than watch someone with more 'experience' fcuk it up? If this is the case I would suggest you avoid BCY and his quasi-flight school/cost sharing/charter/generally slack environment. Ask around at the school you learnt to fly at or another school in your area I'm sure there would be someone who would be interested. For further reference on BCY consult search page and type in 'ICUS Hr Building'. All the best with it though mate.
