Medi - I have done quite a few spinning classes. I know what you mean - they are very tough, harder than one would think.
Congrats to all of you who have quit the coffin nails. Besides the instant cash savings you have made a huge difference to your health, not to mention giving up the stench of burning tobacco and the lingering odor on your clothes.
My change saving helped me alot. Up until a few months ago I had an old texas mickey bottle I would put my change in every night. It took about 2 years to fill it. I last emptied it in November 2011 and it added up to over $600, paid for all my spending money when I went to Cuba. I had this bottle ever since I can remember then it got knocked over and the neck broke off shortly after I emptied it. I had a very large beer stein which became the new container but it is already full, need a bigger container. With the toonies and loonies saving change can add up to big $$ in a hurry.
