I made up a brochure for our HOA. It was posted up front at the entrance. It was not only for the members but also potential buyers. In your case, you may want to modify it to be more of a "About town" brochure. If I was you, I would instead contact your local visitor's bureau and see what information you can gather from them for that information. Local Hotels already provide similar information in their rooms. I know when I go to a hotel there is usually a list of local places advertising. Sometimes it's in the front lobby.
As a former President, you NEVER EVER stop getting questions. It's part of the job. What got me through it was the fact that I made the job a "lifestyle". It was just part of what I do and what I was. It's much like being a cop or a fireman. It's a job but also a community responsibility that doesn't stop when the board meetings ends.
I like the welcoming committee idea. That could be a direction to take this in. New people could get a basket of treats or garden bulbs with a local guide. Plus it's a good time to give them contact numbers and a general rules list of the HOA. Giving someone a source of information other than yourself may just be the help you need.
