I did a check on gunshows in Minn.; now 20 years ago, I used to go to two every year and another three to four every two to three years.
There used to be, at the Minn. State Fair grounds, two Minnesota Weapons Collector Shows every year, I would try to get to one, plus another MWCS show in St. Paul or one in Minneapolis every year. (I was member twenty years ago)
The St. Paul one ended about ten years ago, and the Minneapolis one about few years earlier. St. Paul was the last MWCS show I went to.
The Fair grounds ones I would go to, were on every year, for decades and were the best ones in the State, one was , quite brilliantly, held at the same time as the Spring Flea Market show was held also at the Fair Grounds,
The wives goe to one, the husbands to the other, only 300 feet apart.
Both Fair Ground shows are gone.
Of the numerous ones, put on by any org., I knew existed , every year ten years ago, only three are still around
A lot of new, to me, ones, are now in small, small towns literally in the boonies but sadly most are 100 miles away from me.
MWCS is now down to 5 shows from seven or more twenty years ago; one is back at a place they had not been to for some time while the other four are repeats at two places that are new , to me.
Two are within two miles of me, so , no reason not to go and a good time to rejoin.
Sioux Falls, South Dakota has a good one I went to several time ten years ago, might try that one , depending on weather and money.
