I would like to replicate this:

```
<a href="thepledge.html" class="btn btn-inverse btn-mini btn-ten"><i class="icon-pencil"></i>Take The Pledge</a>  

```

I tried this:

```
<%= link_to("Take the pledge", root_path, :class => "btn btn-inverse btn-mini btn-ten")  do %>
   <i class="icon-pencil"></i>
<% end %>

```

But it gave me this error:

```
NoMethodError at /
undefined method `stringify_keys' for "/":String

```

At the `link_to` call.

Thoughts?
