I went for my first swim with my fin today as my local pool had previously said they they would allow fins but not tails, After 10 lengths (best lengths in my life but I don't need to tell you guys that) the duty manager came over to me and told me I had to take it off he did allow me to do one more length and told me that I might be able to book a lane but would have to phone in the daytime... I think the reason it was suddenly not ok was because a teacher said out loud while pointing at me "thats bloody dangerous" and then probably complained so unlikely able to swim there with my fin any more...
@ Samantha Sleeman Where do you swim? Bristol isn't far from me and I could probably make it over there occasionally
