Multiple Http.Get hanging randomly

I am trying to learn Golang and took on a simple project to call all the craigslist cities and query them for a specific search. In the code below I removed all the links in the listingmap but there are over 400 links there. So the loop is fairly large. I thought this would be a good test to put what I am learning into application but I am running into a strange issue.

Some of the times most of the Http.Get() get no response from the server while others it gets them all with no problem. So I started adding prints to show how many error out and we recovered and how many successfully made it through. Also while this is running it will randomly hang and never respond. The program doesn't freeze but the site just sits there trying to load and the terminal shows no activity.

I am making sure my Response body is closed by deferring the cleanup after the recover but it still seems to not work. Is there something that jumps out to anyone that maybe I am missing?

Thanks in advance guys!
