Your Third is where I got started. Classic Car Clubs Drive -Ins. They came and asked me, I swear I did not know they existed. LOL
Led to more and more. All free. The biggy is they sponsor a once a year car show. I was only vendor for the whole show, because I was there on their Drive -In Nites. Free also. Did a killer thing once a year. Hot Dogs and Classic Cars go together. I got the bug after that. It will take you at least two years or longer to book for everything. Do not just go and find stuff and book. I could do that everyday, look. At the end of two to three years, Then you have to sit and look to see which is profitable and what to throw away and keep working from there. Adding, networking and always looking. If done right really fun and profitable. I cannot or anybody else tell you what is right for you. We went in blind and lost afew but the outcome at the end of the year was in our favor.
Also have to add go to Rest. Pro Section and look -up and Follow Konnie. He did small stuff close to home.
Hope he is doing well, haven’t heard from him in while.
