Just saw Albie's note and concur in principle. In my case, I live in the area so wasn't in a hurry. My first ch-ride got WX cnx, so I had a few extra days to prep and sandbag sims. On that time-line, the ck-ride was cake. On the original date, it would have been a bit of a thrash. The get-er-done in a weekend is doable, but not ideal.
