I went to the Ring twice, euro deliveries for 335 and M3. Aside from the eye candy in the paddock, what I found utterly fascinating was the palpable buzz of excitement in the air, the friendliness of the drivers.
There were motorcycle riders crossing themselves before buying a ticket, sweaty palms and nervous glances everywhere, you can strike up a conversation with anybody.
I once met an American expat who instructs at the Ring, he drove my 335 once and instructed me ona couple more.
It's like no other place, and I will go there many more times before I croak, hopefully.
