I've been spending all of my available money, around £800-1,000 per month on punting. Granted, I've been working hard since I was 13, and I seriously neglected myself for many, many years. I'm middle-aged now, and determined to make up for all the wasted years and lost time. So now I spend as much time and money on punting as I can, and also treat myself to modest meal out and would also like to include a legit massage once a week. Otherwise it's work, be miserable, get old and die. What's the point?
As for the details, it's usually short, lower quality cheap punts near my commute route, and then a longer, modest session in London if I can get one. Stuart has a different strategy which I am considering, which instead of several cheap punts seems to be a single, more expensive but very high quality punt, complete with extras and facials.
