Be aware that your robot detection will not work as it is:

* The question (and answer) is always the same * The answer is in the source code for the site * The answer is only checked in the frontend (so robots will never see it at all)

Effective anti spam should be done in the backend, as a spambot would just send HTTP requests directly to your backend.

The Problem: A bunch of friends and you land up at a bar/wine shop and it turns out to be a dry day and then you go - doh! (one friend even went to Goa for a weekend only to realise it was a dry day)

Solution: I decided to build this simple SMS based reminder service which would remind you of all the dry days in the year!

Let me know what you guys think!
