icalendar devel - Mar 2013 - Ruby newbie, how to access an attendee's email

If an attendee''s inspect reads:

#<URI::MailTo:0xb764a69c URL:mailto:tgagne at xede.com>

How do I (correctly) access the email address by itself?

My objective is to create a webservice I can interact with from 
Salesforce (via REST) that will convert ics/ical attachments into 
Salesforce events, and convert them back.

The first thing I want to do is figure out how to access the elements of 
an invitation to create my event.

My code is at the bottom.  What I''m trying to figure out is how can I 
properly access an attendee''s email?

require ''rubygems''
require ''icalendar''
require ''date''

invite = File.open("invite.ics")

cals = Icalendar.parse(invite)

for each in cals do
     puts each.inspect
     puts

     for eachEvent in each.events do
         puts eachEvent.summary
         puts eachEvent.description
         puts eachEvent.dtstart
         puts eachEvent.dtend
         puts
         puts eachEvent.organizer.inspect
         for eachAttendee in eachEvent.attendees do
             puts eachAttendee.inspect
         end
     end

     puts
end
