Thats the beauty of the way these things usually go. Pick a route you like and bring a few folks with you. I plan on doing some of those roads but not that exact route
Sorry for the long post, but I haven't seen this up for a while so I thought I would update my status and see if anyone else has changed their mind...
I rented the 337 River House at Frio Pecan Farm from Thursday to Sunday which has a house and a bunk house. Sleeps 20 all together. It looks like all of the beds in the house will be full, but if you need a bed in the bunk house there should be some available. PM me and let me know. So far my group will be 12 people on 9 bikes (3 Rockets, 1 Can Am Spyder, 1 Triumph America, 3 HD's, and 1 Yamaha Vstar). My group will be leaving my house in Brookshire, Tx on Thursday morning at a reasonable hour so that we can get into Leaky with as few problems as possible. My truck and trailer will also be going as I have never been to the Sisters when we didn't have at least one bike go down and need to be hauled home, which means someone else may be leading the ride down to Leaky, but I will certainly be on the same road (hoping I can talk someone else into driving the truck).
If you are coming out of Houston or would like to meet our little travelling menagerie on the road somewhere. Send me a PM and we can make arrangements.
