It all depends.....where do you live? Do you have a car or are you looking for something you can ride to?
There are spots everywhere in this town. Downtown just happens to be super fun because there are many good spots concentrated in one area. You just have to look for stuff. The bayous are great places with all the concrete enbankments and lips. You just have to go out and look for the stuff. I just look out the window as I drive around and make mental notes of stuff I see. I then try to go back and hit it up. I found a spot at 59 & 610 that looked really fun but when I got there, it was not really rideable. Too steep of a transition and tons of glass everywhere. My idea of a street ride is just striking out on the bike and seeing what you can find. Sometimes you find a great little lip, sometimes you don't. With heavy rains predicted this week, won't be able to ride the dirt so maybe we can get another downtown assualt going this weekend.
Did you ride DT just this last Friday (the 21st) with a group of guys? Some of the guys I ride with were going down there.
Downtown, all along Allen Parkway and the parks and trails along there, the Galleria at night or early early morning because of traffic, some of the local malls have some good stuff, there is the Easy 7 - Watonga Skatepark...it's free and has the adjoining bayous, its located at 43rd street & Watonga just one block West of TC Jester, there are some fun places in and around Rice Village and West U, there are also several free skateparks around town, most of them are small but you can have some fun, Watonga is the largest and most fun. I'll try to find that link..search for Houston Parks and Rec Dept. and it will tell you where they are. Careful as a couple of them are in....ahem....not so nice areas.
