There is also Plymouth Creek. It is 10 minutes or less from GGGT. Take the GGGT exit onto 169, go south less than a mile until you hit 55, take that west until you cross over 494, and then head north on Fernbrook. The course will be on your west side.
Plymouth is a 12 hole that will definitely test your ability to not hit trees but should not completely frustrate you. It is far better than Bassett. The only issue you may have is that it might be sloppy if the snow is melting.
I know that it does not help you now, but in the spring when the Three Rivers courses open, you will have more choices on the west side.
I concur that if you are coming down from Pine City that BRP will be worth the trip. They do have a Pro Shop there, but the prices are generally a dollar to two dollars higher than GGGT. I do not know at what point from Pine City you would have to get on Highway 65, but once you are on there, it should be easy to find.
Otherwise, if you are coming down I35, you still have other choices.
Lochness in Blaine is right off I35W. Not a premier course, but it will test your long game. It is only 9 holes but they have 3 tees for each one, essentially making it a 27 hole course. Holes 1, 2, 5, 8, and 9 even from the short spot are over 400 feet long. Most of those from the long spot are over 700 feet long. It will test your long game, but they are not completely wide open field shots. While most of them are relatively open, they do have squeeze points. Holes 3 and 8 are basically a crap shoot unless you have perfect pinpoint accuracy.
Acorn is a few miles east of I35W, and is only a mile from Fairway Flyerz. An older course and not in the best of shape, but it is an enjoyable course because it still has enough challenge. While not open field, it has open fairways making it possible to park most holes with above average shots.
There are several smaller courses that are on your way to GGGT like Silverview, Hanson, Sunnyside, and Central Park. They are great if you want to boost your total course count here on DGCR. Most of them have one or two really nice holes surrounded by several non-descript ones. You should be able to play multiple rounds rather quickly if that is what you are looking for. They are great for testing out new discs as it is hard to lose discs there, but if this is a rare trip for you, again unless you are boosting your course count and playing several of them, they may not be worth your while.
I am not ragging on Kaposia or The Valley, they are great courses, but if you are making GGGT a necessary trip, getting to those courses during the weekday from Golden Valley could be a nightmare. 62 is generally stacked both directions, 494 is a nightmare nearing Highway 100 and 169, and 94 between the downtowns is rather hit or miss (either 15 minutes or 2 hours).
Those two courses, along with Red Oak, might be worth your while if you are willing to hang out at Air Traffic in Burnsville. They are having a disc swap from 5 to 8pm. They do have some discs and their prices are acceptable, but again not as good as GGGT or quite the selection. I have not cleared it with my wife yet, but I am going to try to make this disc swap but not likely showing up before 6:30pm.
