Question: set up string collection params

[alexw668]

Hi,

I really like your gem for dealing with the MapQuest API calls. I am trying MapQuest::Services::Directions and have a need to set the avoids option. The API says it's a string collection, so I thought I could do this

map_quest = MapQuest.new "my key"
from = "1 Infinite Loop, Cupertino, CA"
to = "1 Hacker Way, Menlo Park, CA"
response = map_quest.directions.route(from, to, avoids:["Ferry","Approximate Seasonal Closure"])

but my request ends with an error message claiming that invalid value for parameter 'avoid' and valid options are: [toll road, unpaved, ferry, limited access, approximate seasonal closure, country border crossing]. How do I pass such a string collection to avoids option?

Thanks,
Alex
