The man said he wanted to do it at Solstice, and look through it at sunrise. I've done the logo now, so either you'll have to miss your Stonehenge fun or I'll have to move my sun...
The solstice dawn is on a Monday morning, next year, so if we build Gordon`s Trilithon on the Sunday, he can see the sunrise through his trilithon and I can nip off to see it through mine!
