So, you'll most definitely wanna stay back at least 100 feet. Not for any other reason than I'm just learning this new street food business and although a pro at street food, there are some ins and outs that I've not yet got figured out.
And I'd hate to have to do a 180° turn on ya and you end up making the same mistake I just made. It's all a learning game. And I have put all the nitty gritty so far - right here: https://learnhotdogs.com/im-starting-a-kettle-corn-business/
I'm excited for the adventure and look forward to sharing it all with you.
It's definitely a money maker and a full time living for many. Because of Vendors United, I'm able to talk to thousands of vendors and I have already talked to many about this.
If you end up catching the "corn bug" then I'm sure you'll find this extremely helpful in avoiding all the learning curves - that I'm currently going around now.
