I’ve posted elsewhere about my personal reasons for particularly enjoying this challenge, but for what it’s worth I think it’s a great concept.
The 5 mile radius made me really think about what to include, but it was still very much an achievable goal. And that’s with approximately half of my 5 mile circle falling within the Norwich Airport FRZ.
A repeat challenge would get my vote, and hopefully might generate a few more entries (though 8 isn’t a bad haul so far to be fair).
The only thing I might suggest is having the discussion and entries thread combined. I know there were reasons for separating them out, but if everyone is discussing and submitting entries in a single thread then it keeps said thread near the top of the Challenges category with a higher turnover of new posts.
Again though, really enjoyable challenge.
