I've been enjoying Learning with Learn. This lesson was useful as a chance to get used to putting the pieces together. I created a gem to extract the current local weather from weather.com. Avi's video helped a lot here and it was great to see how one can think on the fly and try things out in this context. And I learned from watching him put to together methods which helps underscore how the pieces work together. I liked laying down a concept for the gem in notes and stepping back for a second to think through the aims of the gem.
I think I chose a difficult site for this project as it uses angular js. I really struggled with scraping and needed online chat help on several occasions. On the recommendation of Adam King (ADAMKING0126), I looked into Phantomjs to scrape the text I am interested in. I installed it on my computer and also followed some online instructions for installing into my gem via command line. Unfortunately, after a rather long install I received a number of messages about Phantomjs not being able to be installed on my system.

I don't feel great about stopping here but I did spend several days on it and I did get something out of using Nokogiri, conceptualizing a gem, working with requirements and building methods. The next steps would be to work on zipcode search functionality and add something like a 5 day forecast.
