I was very excited to return to the Walker. Unfortunately I left after about 5 minutes. I was assured, when I purchased my ticket that visitors would be required to wear masks. This was not the case. Many children running about without masks and adults as well. The adults put their masks on at the entrance and as soon as get to the galleries take them off. This endangers other visitors as well as the staff. Very disappointed that staff does not ask unmasked people to leave.They have since this was written become more alert to this problem and are taking action.
