A tripod

I bought a tripod today (a Manfrotto 190XPROB), so I went out and tried it. I went pass the royal castle and took some photos there, after a while two of the castle guards came and asked me if this was for private or commercial use, apparently only photography for private use is allowed there and apparently my gear starts to look a bit too professional :-). Anyway I just told them it was a hobby, and everything was ok.
