Unknown trek for 2-3 weeks

I just now decided to fly up to Nepal, so my plan is lacking any definition as of now. I want to hike 2-3 weeks somewhere the flowers are blooming and butterflies hatching. Good views. But I am not picky. Maybe Anapurna, not sure if I will have time for ABC, but looking for more info and buddies. I will have to rent most of my gear since I have been traveling 18 months already. I like to hike steadily, but I have bad knees which makes downhill slightly slower. I like to have good philosophical talks while hiking and have been known to sing…
