Here are a few general suggestions about going to a trade show...
First, consider a trade show trip to be an investment of your precious time and money, and make the most of it.
Second, plan. Read the class descriptions carefully, compare the content and the instructors, and make informed decisions about which classes are best for you. If you have questions, contact the instructor and ask.
Third, take advantage of the opportunities to meet and connect with other framers. Socialize. Acquaintances made at these events may develop into personally rewarding long term friendships.
Fourth, retention is important. Get a good night's sleep before a day of classes. Take notes and keep the class outlines/handouts for later reference. Getting it in class is not enough -- you need to be able to take it home and put it to work in your daily business.
One more thought:
Between classes, patronize the exhibitors who spend huge amounts of their time and money to bring their wares to the trade show. They subsidize the classes that attract so many framers to WCAF and the other trade shows. They need us, we need them.
