We stayed last week for 4 nights, including a Saturday when we attended a concert at the Barbican theatre. This finished at 10.15 so we knew the back gate was locked (still confused as to why a locked gate needs to be padlocked anyway.....??). We walked back to the site using the suggested route (Millennium Bridge) only to find approximately 150 teenagers/youths having a large gathering/party stretching across both ends of the bridge. We had to endure numerous offensive comments and aggressive behaviour as we walked past them - one of the most intimidating experiences we have ever had. My advice to members is to avoid the area after dark and invest in a taxi - it's worth the money, believe me, and had I known what was about to happen, I would done that. I have emailed my concerns regarding Member's safety around the bridge area to the CMHC but as yet no reply. We love the site and have stayed many times, but will not be returning until the flood work is completed....or alternatively, the CMHC comes to their senses and stops padlocking the safe route back to the site i.e. the back gate.
