Ah, I wondered if this was the case when I saw how big that message was. This isn't a "true" SVG, as it just has the image added to it as an image, which you can see at high zooms:
What you ought to do is take a true SVG of the logo and add that instead of the image. Of course, this SVG looks like it was a quick image → SVG conversion (you can even see the pixel edges that didn't smooth correctly, and the Illustrator tool is mentioned in the SVG metadata), but it's still preferable to the embedded image, as it will not blur.
It's probably not your job to do graphic design for the USFS, but if you can't find a "good" SVG, you can always do your best to replicate it using something like Inkscape, where you can actually create curved text elements.
The SVG I linked to above is still just shy of 100k characters because of how it was generated. However, even a really basic (and admittedly not very good) SVG that replicates the same features can come in at around 7k characters.
