Congrats mate. You've got lots to look forward to. Been there, done that, no major regrets. Of course there are things I miss about HK, but weighing everything up I made the right decision to leave when I did. I went for a BMW myself, and my major project now, I bought this empty block of land and building this double story home on it for half the cost of my HK shoe box.
Actually I cannot recall off the top of my head if Geo has a regular poster based in UK? We've got Hull in PH, TheBrit in Japan, CWBGuy in Malaysia, Edward in Portugal, Skyhook covers east Australia, I cover the west, etc. So I think you'll be covering a vital region where we are a bit thin on the ground at the moment. In other words, dont leave geo!!
