THIS IS A MUST RIDE > You will come back feeling you want to ride it again.
How to get there:
North of San Antonio, take IH-10 to comfort exit, take a right at light, and travel under the highway. Take the first left (road). You will see a yellow street sigh with a mountainbike on it. Travel to the very end of this road. It will get very narrow (one lane) and lead you to a gate. Open the gate and stay to your left. You will see the Logg in board, with one restroom near by.
