It's really hot and humid. No way around it.
As much as it's oppressive relative to what we are used to, most folks today (even employees) found it more fascinating than anything. Definitely high-end stuff for an uncomfortable period.
I do think it was worse last year up here.
Early July 2018, MVL had 4 out of 5 days registering a high of 92F (today's high was 91F), which is incredible to get 4 days up this way in the low-90s in one stretch...lows of 68 and 72 at a radiating site in there too, which means dews were high (last night low was 69F for comparison).
