Thank you all so much for your input! I truly appreciate it all - positive & negative - that's why I asked on here. I knew everyone would have an opinion. After reading your replies, I realized I hadn't been specific enough. We are considering a school bus, and it would be big enough for people to shop inside. That's my plan - a mobile store. Farmer's Markets are wonderful ideas - thank you for that!
Keep the comments coming. I will certainly be doing more market research and I've already discussed it with my accountant. Not sure what the future holds but definitely looking forward to it!
