I just saw this posted a few minutes ago. The article says it won't affect the use of the park, but I think I'd like to see some maps showing just where they plan to put the power lines. Here's the link:

Even if it doesn't close any trails permanently, if they are putting in new lines, it seems likely that there would be temporary closures if they go overhead.
