To be brief, Mike, but restate what I already posted,
those current health elements which include
- concern about groups of more than 10
- concern about close proximity -- less than 6' spacing -- of individuals
- the use or non-use of masks in conjunction with 6' spacing
- severity of outcomes for anyone with pre-existing conditions or advancing age
all make for poor group dynamics for the typical wedding of the past, with
- groups of 100-400
- individuals in close proximity, including desired involvement for very elderly family members of the bride/groom
- inability to wear masks while drinking and eating
- crowded dance floors
because we do not yet have a means to
- vaccinate -- with proven efficacy
- test enough of the population, repeatedly and with sufficient frequency to detect current actively infected yet asymptomatic persons
For risk-accepting somewhat youthful wedding participants and guests, that might work 'If I get sick, I will recover"
But that fails to address the presence of grandparents and parents and others with pre-existing medical conditions which place them in the vulnerable population of guests.
How long will groups of more than 50 be too risky to authorities?
Until all of that is sorted out, the wedding market in general is in dire straits. Hopefully, on the Pro side, the bride's family spends less on festivities and puts the money into a home for the new couple, instead. Less 'wasteful', IMHO.
The photographers who cover them can begin even with wedding groups limited to 10, who sit widely spaced while they eat or stand far apart while they drink strong enough liquor to destroy the virus intake thru the mouth, but grandad and grandma (maybe even Mom and Dad) cannot be there unless they shelter in the corner (and from the well documented and analyzed case we know that is insufficient!), and limit mixing to masked encounters with frequent hand washing. We don't want weddings to be like living in assisted living homes, with huge outbreaks because we bring in lots of folks from all over for these events. Since less money is spent on food and booze for guests, it is relatively easier to ask for the same amount of money for 6 hours of wedding coverage.
Lastly, folks need to be able to pay for weddings. A lot less of those are around right now. According to History, the Great Depression suffered 25% unemployment, and even at the beginning of WWII about 10 years later the levels were 15%...unfortunately it took a world conflict to get the economy on its feet once more and into prosperity. Hopefully we can recover faster this time, without the world conflict.
My one daughter is also in the frontline everyday and they don't have enough masks to hand out so she had to reuse hers for 4 weeks at a time. I pray for her safety everyday.
