find land owned by another business. Assist them in building an Electric offroad track with stand. it will cost them about $15000 all in (amb, computer. pa system, stand, earth work.)
then get a committee to run the track and let the business recoop the costs. the business meanwhile will benefit from more traffic/advertising, and if it's a restaurant, more clients.
it's ideal for diners that are on 2-3 acres within a 30 min drive from urban centres of more than 150 000 people.
it has worked for us.

getting new people into the hobby is best done by "bring a friend" day and get the inviter to have a rental RC car for his guest for that day.
that's worked best for me. I've gotten about 6-7 people back into the hobby and about 4 newbies
