I feel your pain! I'm 5'1.The last concert I went to was 2 years ago, I was 27 and was refused entry to the beer garden
Also when I came over here after a visit home when I was 20, I made it to Heathrow and my airline was on strike. The man at the desk called the other airline and said "I have a girl here about 13 travelling by herself, can you make sure she is on the next flight". I allowed myself to be 13 for the next few hours - nobody looked for ID, or at my passport and I was given the direct number for the manager working at the time. I was more or less escorted and helped directly onto the plane There are benefits!!
I do like that almost no horse is too small for me. At 92 pounds I can even school a shetland for a short time without any problems xD
