now i would like to see this mans dream being fulfilled, it is a great cause.
if nothing else works, thry getting funds in other ways. ,
examples
1 have little kids draw motorcycles then sell the drawings.
2 maybe go to the store they will give you a big discount, or even extended credit time ,
just so the bike would be in your fathers hands. on the desired date. the bikes are overpriced at the dealerships so they wont care if they drop the price lower for you. as long they can get the goods out of their hands . for the next hot stuff.
3get organised you with help of friends can definitely make a plan to get the money.
maybe open errand shop, where you sell services and do errands for people.
4 sell flowers flowers., sell anything.
5 if you cant get the money by the date, you can at least rent the bike, so the father could drive it for a week or just even for a day.
cheers.
