I've gone ahead and bought 4 strips of the cable guard recommended by Stub Mandrel for the Bash to complement the rubber guard I normally bring. Apart from the aspect of keeping tape off the floor, the hall Trustees have been having a blitz on risk management and I'm having to do this as I've assessed tripping over cables as one of the main risks of the event.
As everyone realises, the Bash has always been priced to break even. I'm therefore asking/inviting/imploring/begging (delete as appropriate 🙂 ) everyone to pay an extra £2 on the door to help cover the £68 unexpected additional cost. At £15 a head, the Bash is still a bargain. (If anyone isn't prepared to contribute, that will be OK too.)
No need for discussion on here about the above btw. Whatever happens on the door will be fine by me.
