That's eeeasy one shim, get on't big boat...less miles driving, more relaxing, less dosh, fair intro/trial run at Zandvoort plus easy relaxing journey home from zolder.
Don't forget to add miles on track per £ in transport whilst also giving more weight per mile on fresh/new tracks into spreadsheet! Plus if there is any easier work admin you could do 3-4 hrs on boat. Increasing productivity is the only way out of the reccession
Me, curly & twiggy will wave as our boat will be right behind you and we could either all drive up to zv or meet you there.
