What state has the highest ratio of courses rated 4 or higher to square miles? That would be the state that I vote for. I don't care enough to do the research myself, but if someone does care and has the time, then I'll vote for the state that you come up with. Until that time, I vote TEXAS!!!!
Okay, I took the time after all. Here's the rank that I came up with by looking at the number of courses with at least 10 reviews that were rated 4 or higher compared to land area of the state:
Top 15 States for Disc Golf:
1. Connecticut - 1 Excellent course every 5,500 sq miles.
2. Maryland - 1 every 6,200 sq mi
3. Pennsylavania - every 7,700 sq mi
4. Kentucky - every 8,000 sq mi
5. Massachusetts - every 10,500 sq mi
6. North Carolina - every 13,500 sq mi
7. New York - every 13,600 sq mi
8. Virginia - every 14,300 sq mi
9. Tennessee - every 21,000 sq mi
10. Ohio - every 22,500 sq mi
11. West Virginia - every 24,000 sq mi
12. Texas - every 24,500 sq mi
13. California - every 27,300 sq mi
14. Georgia - every 29,500 sq mi
15. Oregon - every 32,700 miles
Without factoring in square mileage and just going by sheer numbers of courses rated 4 or higher with at least 10 reviews:
1. Texas - 11
2. Pennsylvania - 6
California - 6
4. Kentucky - 5
5. New York - 4
North Carolina - 4
7. Oregon - 3
Virginia - 3
Based on these numbers, I'd say the two leading contenders are Pennsylvania and Kentucky.
