Warning/Caution re Broomhill Flash

Hi,I visited Old Moor yesterday on the way back to Castle Donington, Derby I called in to Broomhill Flash inside the hide were two youths no binos etc but 2 cans of lager and no conversation. They left 5 min later and I left 10mins after and I have to assume they had stabbed my rear tyre twice in the sidewall (the local garage called it spiking) so just take care. Steve
