Saving carrott seed

Hi all. Just got back from my holidays, to find this little beast amongst my carrot bed.......

It's definately not Queen Anne's Lace!

I can only assume, a rouge carrot must have germinated last year, and overwintered? ( I grew Caulis there last year, with Runner beans in the next bed???  ) 
Now, My question is, can I save the seed easily? I have been having a root round the interwebby and I think it's  all about cutting the drying umbels off and drying further, before harvesting the seeds.... Has anyone else tried this?

Thanks Salmo, Onto the compost with it then!
