Thanks to everyone who chimed in in comments below or by email. The majority liked the hanging idea, and in searching Store Supply Warehouse I found a rolling rack that measures 4’ wide x 2’ deep and folds flat for transport. We’ll have that in the next month or so; hopefully will pick up when we are in the Harrisburg area and save freight costs. Will post pictures after the show at York, PA in June.
Regarding business, I contacted a SCORE counselor with questions about setting up at Houston. That won’t be this year, but I will be learning more in the next weeks and months, and hope to be able to go to Houston in 2011. So far, while the counseling has been a reality check, I’m not yet ready to throw in the towel – rather, I’m energized! “Watch this space!”
