Whether because of distance or steepness or dread, these hills certainly influence our bicycling discussions.
A consensus of Don Teator and Chris DeGiovine, this quite subjective list recognizes the lingering memories and moods these hills have afforded us.

Top Thirty	in or close to Greene County
Adirondack	a limited list because of Don's fewer rides there
Short Snots	not long enough to be Top 30 but still "fun"
The Future	these await us

1. Devil's Kitchen - two miles of tough, especially the horseshoe
2. 23C east from 23 (Maben's Airport hill) - doable first half mile, stupendous wall for second half
3. Sickle Hill - unrelenting mile and half
4. Mead Mt (Woodstock side) - two miles in your face
5. Susquehanna Turnpike from Durham - rolls bookended by steep sections
6. Peekamoose Hill - tough climb from the Ashokan
7. Cass Hill - switchback heaven, and more to come
8. 23A from Palenville - three miles of steady pressure and traffic
9. Cheese Hill Rd, Preston Hollow - a long grunt from Rt 145
10. Ohayo south side - switchbacks galore with view of the Ashokan
11. Potter Hollow, Gilboa fork - testy path that's tougher than expected
12. Sutton/Cunningham Rd - not unlike Susquehanna
13. Rt 156 from Altamont - long, steady grind
14. West Fulton (CR 4), from Rt 30 - snappy test, especially if going to Cobleskill
15. Kropp Hill on CR 358 - classic head wall at end
16. 23 to Pt Lookout - four miles of grind, nice views of the valley near top
17. CR 2 west to Prattsville - the tough way to get to Prattsville
18. Potter Hollow, Broome Center fork - three miles of steady grind
19. Cole Hill, north side - a worthy test that confronts within view
20. Powell Hill, from 143 - a challenge to stay on bike, higher rating if longer
21. Sunset Hill, from South Westerlo - steep top and bottom, with little rest
22. CR 10 Prattsville - 1st and 2nd hills together, separately - might not be on list
23. Middleburgh 145 north - a whack across the head, expect it to be not so tough
24. Schoharie 1A - steady push past Guernsey's Nursery
25. Middleburgh 145 south - mile long test, often done in baking afternoon sun

Others not close by, but would be our Top 40 if they were
Bash Bish Falls Rd - a worthy climb, need to pace well
Rt 23, state line near Catamount - long and steady
Winchell Mt - from Millerton, mile grind out of the valley
Rt 199 from Millerton - steady grind
Mohonk Mt House Rd, both sides - classic big hill climb
CR 52 to or from Cooperstown - steady grunt 
Otsego Co Rt 165 between South Valley and Dorloo - 55 mph downhill

Worthy Adirondack Hills

1. CR 8 to Hague, west side - long, long grunt
2. Tongue Mountain hill from Silver Bay - steep wall in face
3. Benson hill - steady grind in southern Adirondacks
4. Keene up to Lake Placid - classic long grind
5. CR 8 from Wells - miles of unrelenting pedaling without a break
6. Rt 28 from North River - classic uphill state road
7. Hague Rt 8 east side - (have not done but judged from downhill ride)
8. Blue Mountain, up past Adirondack Museum - short and "sweet"
9. Riverbank Rd from Bolton Landing - one tough & gradual hill after another
10. Blue Ridge (No. Hudson-Newcombe) - long climb, classic hilly views from top

Short but Worthy
- German Hill - from CR 41; classic half-mile springtime test
- Sunny Hill - (east side) feels tougher finishing up home
- Maplecrest Hill - from Maplecrest; one steep switchback
- Cornwallville Rd -  from Cornwallville to Rt 23; always tougher than expected
- 20B Cornwallville Rd -  from East Durham; almost as tough as German Hill
- Rickard Hill - by Schoharie school, view of the quarry
- Hervey Street Rd - a slap in the face after a medium climb
- Jocelyn Schoolhouse Rd - not really tough, but not nice after climb from Altamont

Worth a Visit, We Have Heard
     Local:
- Big Indian - have come down, expect it to be tough
- Highmount, Rt 28 - visual toughie
- more of the Helderbergs - classic word of mouth
