Glenb, you really know your stuff! One might assume you're involved in pilot instruction in some way.
Thanks for all the pointers guys. A few varied opinions here, I think with age comes wisdom and part of wisdom is knowing when you don't know enough. I think as a young guy I would have flown in to weather that I knew was sketchy but now I would be overly cautious. If there were a situation that I was at all unsure about I'd be on the phone to a pilot mate or one of the more knowledgeable local pilots. Either way I really do appreciate your concern! It really seems that aviation is one big family, such an awesome industry.
GST is not such an issue for me as my company is paying for my pilots license as part of our "Diversification Strategy". Ahhh the benefit of having a great accountant.
I'm on the 150hr though so I may have to chat with the school about it. Just thought it would be a cleaver way of integrating it in to my training!
Thanks again for all the great advice!
