James,
I do not have anything to do with the actual event, it was published by our local club and I deal with Riverside on a regular basis. I would say it will be small, but Bob has a tremendous amount of Spriget and Healey parts, he also rebuilds transmissions. I am sure the locals and others will show up with more. I look at it as an opportunity to meet local LBC people and others. Give Bob a call if you are looking for something special 614-378-8153
I'd make a 2 hour drive! You never know who you will meet or what you will find.
Mark
