East & West Coast Reunion?
If the numbers are large enough this group might consider an annual gathering like the American Lancia Club Reunions held on each coast. Great fun, with the usual show and shine plus a rally, and also family activities. We attended the 1983 event held in Cambria, and ended up moving to the area in 2001. There was a great selection of machinery, from Appia sedans so cute you want to take one home, to a rip-snorting Stratos that swapped ends twice during the weekend with little warning but suffered no apparent harm.
The ALC events usually had about 50 people attend, but if our numbers are small it would make sense to see if the Sharkfest group will accomodate us.
