It took me around 250 steps in 2 hours with many breaks and a lot of effort to get me up on a 70 high blast furnance. I am on a industrial area in Germany today. I wear a super tight jeans and a nice striped shirt and I feel so big walking between the handrails. Usually there fit 2 people side by side, but see me taking all the space for 2. Waddling up and down.... fun! I just was hoping there wont come people ... hehe... they wouldnt fit next to me.
