On March 7th and 8th I will be at the South by Southwest Education conference in Austin. Another conference that I have enjoyed is the ISTE one which this year is in Denver from June 26-29. The key, if you can do so is to find someone else to pay for you. For example I am doing work for TES (more on that coming later) and so they are paying my entry ticket.
So why bother? Well first off you will meet lots of tech minded people like yourself and make some connections that you can work with when you return home. Secondly there are lots of companies showing all of their latest wares and then, there are talks and demonstrations - literally hundreds of them.
If you can't get the big ones, look for one close to home. Here is a place to start.
