Things this week:
TNG – WE NEED SELLERS
TNGFest – APR 7TH
This week there will not be a ZOOM meeting.
WE NEED SELLERS. Even if you only have a few things, bring them.
The fest portion of this will be from 7pm till 8:00 - 8:30 depending on the activity. After that we will begin our auction portion of the event. DISCLAIMER – none of us are auctioneers so it will be a gentleman’s event – no fighting.
If you are going to sell PLEASE email me, [email protected], by ASAP. So I can plan on how much table space to devote to the fest.
We have no idea how many of you are wanting to sell stuff, nor do we know how many buyers will be there. PLEASE limit the number of items you are bringing to what would fit on one of the tables.
If you are bringing heavy stuff – bring a pad to protect the tables.
You will be responsible for damage to the tables.
Everything you bring MUST be sold, given away or trashed. There is limited trash bins space at
The clubhouse, so you may have to take it back home.
DO NOT bring anything you are not willing to take back home.
PLEASE do not arrive before 6:30 P.M. to set up. The tables have to be rearranged BEFORE the event.
If you are NOT selling PLEASE do not show up until 7pm.
WARNING!! - May 6th DARA membership meeting will be home brew night so get projects ready!
Even though mask are not required feel free to wear a mask if you feel more comfortable. There will be some wearing mask so you will not be the only one.
The pop cooler has some pop and water.
PLEASE if you are having any of the COVID symptoms DO NOT come to the clubhouse.
