I applied for entry into Canada and was denied due to a DWI I got in 1979 when I had just turned 18 (I'm almost 53 now).
On a whim I decided to try again and put together a packet containing personal /financial info and included a polite letter asking for reconsideration. Sent it in via USPS Express mail.
The packet included the original denial letter.
Today I received my stamped entry permit with permission to enter Canada.
How cool is that?
