When I saw that Bruce Long from Colorado Springs had signed up on the website I wondered if it was you, but I was so busy at the time that I didn't follow up. I'd love to have you become an active member on the site. The weekly assignments are a great way to learn. Much of my personal satisfaction comes from seeing how much the "regulars" that participate in the assignments have improved over time. I know there are a lot of "lurkers" out there that are hesitant to submit their images in the assignments, and I wish I could convince them to jump in and start learning.
Yes, I can believe the 800 pictures in one day.
That's the best way to improve. There's a lot to be said for the "10,000 hours" maxim. Lot's of studies have proven that it's not innate ability that results in virtuosity, but in reality it's the 10,000 hours of dedicated practice. (I still don't get enough practice!)
That's a great picture of the canal. I love how the boat dwarfs the canal. I haven't been through the Panama Canal, but from the few other canals I've been through your image does a great job of conveying the sense of "just barely squeezing through."
If you have any questions, fire away and I (or somebody else on the forum) will do my best to answer.
Good to hear from you!
