Feel free to use in publications and pages with attribution but you don't have permission to sell the photos themselves. A free copy of any printed publication using any photographs is requested.

I love well-behaved spiders! They are, in fact, how most people find my site. Unfortunately, my network has a limited bandwidth and pictures take up bandwidth. Spiders ask for lots and lots of pages and chew up lots and lots of bandwidth which slows things down considerably for regular folk. To counter this, you'll see all the text on the page but the images are being suppressed. Also, some system options like merges are being blocked for you.
Note: Permission is NOT granted for spiders, robots, etc to use the site for AI-generation purposes. I'm sure you're thrilled by your ability to make revenue from my work but there's nothing in that for my human users or for me.
If you are in fact human, please email me at guthrie.bruce@gmail.com and I can check if your designation was made in error. Given your number of hits, that's unlikely but what the hell.

- Specific picture descriptions: Photos above with "i" icons next to the bracketed sequence numbers (e.g. "[1] ") are described as follows:
- GFAVAC_031110_16.JPG: Canal Gates
These lock gates and miter sill are the remains of the lower gate assembly for Lock 1. They were constructed in 1820 to replace the original gates and sill that had been installed in 1802 when the canal became operational. The sill and frames for the lock gates were built from white oak and face with planks cut from yellow pine. The gates were originally coated with pitch while the miter sill was sheathed in tar paper to prevent decay.
Each gate hinge post fit into hollow stone channels in the lock walls called quoins. The gates pivoted on iron pins at the bottom of the quoins and were held upright by iron collars at the top of the hinge posts. The miter sill rested at the bottom of the lock pen and provided a stop for the gates. By meeting at an angle, the gates were designed to resist the strait from the water. When closed, the weight of the water forced them tightly against the quoins and sill, allowing the water to leak past.
- GFAVAC_031110_19.JPG: It was a month after Hurricane Isabel. The park had prepared for expected flooding by putting sand bags around the visitor center. They proved to be unnecessary but were still there.
- AAA "Gem": AAA considers this location to be a "must see" point of interest. To see pictures of other areas that AAA considers to be Gems, click here.
- Bigger photos? To save server space, the full-sized versions of these images have either not been loaded to the server or have been removed from the server. (Only some pages are loaded with full-sized images and those usually get removed after three months.)
I still have them though. If you want me to email them to you, please send an email to guthrie.bruce@gmail.com
and I can email them to you, or, depending on the number of images, just repost the page again will the full-sized images.
- Connection Not Secure messages? Those warnings you get from your browser about this site not having secure connections worry some people. This means this site does not have SSL installed (the link is http:, not https:). That's bad if you're entering credit card numbers, passwords, or other personal information. But this site doesn't collect any personal information so SSL is not necessary. Life's good!
