I think you did great!
A couple of tips for attending shows... these only work if there are " out of town" growers.
1. if you know what you want to buy, go early.They show their best stuff.
2. if you're on a budget, go the last day. They will haggle prices because they don't want to pack them up and transport them home, but the selection isn't as good.
3. I always try to get there early in the day, before it gets crowded, so the vendors have time to talk. Most of the shows around here run from Fri. thru Sun., and I'm not on a strict budget, so I usually go early on Fri. Sometimes, if you ask about a specific plant, and they're not too far away, they will bring it tomorrow.
