Normally, if I am looking to play a new course and do a field trip. My search criteria is 18 holes, 3 rating or better and a 100 miles. Than I read through the reviews, print the course map and look over the pictures of the various holes. In the summer months I'll do overnighters or a weekender trip, than the distance increases and I look for the nearest camping.
I don't ever give a course a lower grade because I lost a prized disc. That is my fault not the course designers. In my mind there are two types of courses. Your average run of the mill fun to play layout. It has multi pin & tee locations with ace and birdie opportunities, more holes with open greens with smart and well thought out basket placements. Normally a even distribution of right and left handed pins. The designer did the best with what he had to work with.
The second is a course that will challenge and push me to play smarter and better. Distance isn't so important a factor as is the design. I want to see good terrain changes, difficult basket placements, mandos, direction changes, OB zones and water hazards if possible. Pars should be realistic. I prefer concrete tees or the well secured rubber pads. Natural tees are okay too if level and maintained. I want to have to think out how to play the hole, not just power drive to within 30 feet of the basket. I have to play multiple rounds to find the best route to the basket.
All the rest is just icing for me. Location, nice views, pretty signs, bathrooms, water fountains, parking, basket type. The course should be maintained to a reasonable degree. I understand that rural low volume locations won't be as glitsy as well used courses. I shouldn't have to use a machete to get to a basket. Or watch where I step because the place has trash everywhere. I'm very reasonable about these factors and grade accordingly. I've played some urban parks and understand the limitations of the area.
Optidiscic, if you plan on playing Nockamixon on a weekend sometime in the near future send me a PM. It takes me about a 1hr and 20mins to get there.
