I used to play in a league at a pitch and putt. Two rounds of 18 starting at 6:00 p.m. Even on the longest days of the year, we were lucky if we got it all in before dark. Late in the fall we would play the whole second round in the dark. It was a park sanctioned event, so we were OK to be there. In the winter in was not OK for us to be there, but the Rangers did not work the parks in the winter so we played random draw doubles every Thursday at regular league time in the dark. The park also had a glow tournament every spring and fall. With all that going on, I've played hundreds of rounds of glow golf.
Back then there were no LED lights. We HAD to get glow discs to play glow golf. Fortunately Avairs and Rocs are easy to get in glow plastic, and thats really all you needed at that course. A buddy of mine used to buy these hand-held florescent lights at Walgreens and keep them in his car for sale so it was easy for us to get something to take with us to activate our glow discs. Another buddy found some black light bulbs to put in them that did not light up as bright to help us avoid being noticed by Rangers, neighbors and/or cops when we decided to visit another course "after hours." I lost a good Gazelle one time when the cops appeared right after I threw my drive...we had to scramble to get out of the park and left the discs we threw behind. When I came back the next morning I couldn't find any of them. I've always wondered if the cops found our discs and kept them.
We also had an all-night disc golf marathon one time. We were playing one Saturday night and a guy got toasted..I'm not sure what he was on, but he was on something. Anyway, we were trying to keep him from going anywhere, and the only thing that worked was telling him we were going to play one more round. He finally passed out at around 4:00 am. Since we didn't have to baby sit him anymore, we went out to play one more round! The sun came up before we finished that round, and when we got back to the pavilion the guy was awake and seemed OK to drive home. I forget if we played five or six glow rounds that night, but the glow discs definitely got a work out!
I'm kind of old to be running from cops or hanging around with guys tripping in parks these days, but back in the day we had some great times playing glow golf.
