NaNoWriMo home page there is a tab labeled Regions. When you click on that tab you will find several drop down links including one called Come Write In. When you select it the above page opens up and you can click on the light blue box to find Write In locations. They suggest you contact the location for dates and times. Remember, you home region will list Write Ins as well and they usually have more complete information there.
At the time I took this screen shot there were 1,029 entries. Write in your location in the search box and it will immediately sort out the closest upcoming Write Ins for you. My next post will talk about why attending a Write In can be such a boost.
