Thanks for checking out my post. I appreciate it! I do enjoy the railroad tracks, so I'll keep Richmond in mind.

To address your question, that's sort of a gray area from what I can tell. I personally have no problem with reposting content from an existing blog. I've often seen users end the posts by saying "Originally posted at [url] on [date]" or something to that effect.

I'm sure that as you go back and look through the posts you want to port over, you'll want to make changes and such, and I think that will be great. I do encourage your idea of mixing new and old content, and I think you'll find that you'll start writing posts for Steemit and then port them over to your blog rather than the other way around haha but let's not get ahead of ourselves.

I think sharing the content you already have would be fantastic, especially if you actually take the time to comment on the images and give a well thought out post each time rather than just pointing to your blog link.

I say go for it. Thanks for asking a question. I'm always happy to answer any more that you have!
