Del, Werner,
I understand, and the trouble with the web is that folk think that it's all free, but even Wikipedia needs a donation to keep it going once in a while.
I suspect that many of the people who download the guide are well intentioned and in the midst of getting ready, may overlook the payment. There will be others who don't have PayPal and consider doing a bank transfer quite onerous.
I wonder if people had more incentive then they would give over some money.
Perhaps something simple like redrafting of the redirect page and suggesting that it is worth the price of a beer, and even saying that you have this "labour of love, but...".
I think that the section "On the run - Escaping the traffic at the end of the race" is worth the value of a beer in its own right.
Perhaps a bit of text saying "if you have used this route and saved yourself hours of frustration in a traffic jam, perhaps you would consider a contribution once you are home and thinking about your trip".
Hmmm.... I think I may have found a new job. I'll have a go at drafting a redirect page and fire it over for your thoughts.
The alternative of course is sponsorship, but that's a slippery slope.....
