If you love new and unusual ways to make winter less boring Saturday's 100 T-Rex Boogaloo should do the trick.

According to the Boston Globe the event will take place in Portland's Monument Square around 3PM on 1/20 Saturday. As you can see in the video above from Nashville last October these costumes have become a popular way to colonize a group to have some fun and laughs.

This Facebook event was set up by Alison Cyr and Valerie Sanborn who says she got the idea after buying her own costume. The ladies say they are expecting more than 100 to participate.

In case you’ve never seen a T-Rex dance here is one learning the Macarena.
