You can try something like this:
agent.page.search('.youarehere > a').each do |a|
link = Mechanize::Page::Link.new(a.attr('href'), agent, agent.page)
region = link.click
end
not the cleanest way to do it I guess, but Mechanize is doing almost the same in its source code: http://mechanize.rubyforge.org/Mechanize/Page.html#method-i-links
Would be a nice addition though, instead of going through this.
