This event is being organised by Portland resident Paul Butcher, as a member of region R26 of "Porsche Club Great Britain" {= Gmünd Heritage Limited, a limited company, registeration # 1536536}.
The event is to benefit the "Dorset and Somerset Air Ambulance" (charity number 1078685).
It will also benefit Weymouth in tourism terms (with a similar annual event in LLandudno bringing an estimated £25k to the area, see https://www.porscheclubgb.com/regions-registers/regions/west-midlands/west-midlands/events/2016/may/llandudno-weekend)
There is also the option to do some fundraising for ourselves if we choose + have enough helpers to "shake a bucket" (we would need our own street collection license).
The organiser has also approached the Portland Sea Cadets for their assistance, but has so far had no luck with other Rotary Clubs / Lions in our area.
