    Great presentations. Funny that Nelson and I with others were trying to find building E. Is there not an app for that? My take away was the great work on the battery drain problem. The rest was pretty straight forward but missing one thing I won't mention here.

    Hey gang!

    I am looking to connect with people interested in the Emergency Response and Management space. I’m a proud, experienced, and accomplished geek and you should be hands-on and able to code. I’ve developed an LBS App on Android and would like to collaborate with someone to bring it to IOS. This is NOT for someone who wants to Zoomba with Zuck or Salsa with Sergey. In other words, don’t expect to get rich off of this idea. This is for someone who has a genuine interest in helping First Responders. If interested, let’s connect at the Meetup tonight. You can ping me (BobAtQuimbaDotcom) or look for me at the meeting. I’ll be the GeekDaddy in the black hoodie and shaved head!!!

    Some of you may already know me and might have attended the Mobile Devices in Emergency Response meeting I organized. Either way you can take a look at my LinkedIn page here: Looking forward,
